An 1859 fight over how to make matzah has lessons about the threat of AI today
(JTA) — In the last few months the world has been dazzled by an astonishing sequence of AI systems capable of performing all kinds of difficult tasks — writing code, composing poetry, generating artwork, passing exams — with a level of competence that rivals or exceeds what humans can do. The existence of these AIs has prompted all manner of soul-searching about the nature of humanity. It has also made many people wonder which human tasks are about to be taken over by machines.
The capabilities of these AIs are new and revolutionary, but the story of machines taking over human jobs is not. In Jewish history the most important story of that transition has to do with matzah, and it’s a story that carries important lessons for the present day.
Starting 164 years ago, dozens of European rabbis engaged in a furious debate that would not be fully resolved until the beginning of the 20th century. Matzah, which for millennia had been made by human hands in accordance with the narrow constraints of Jewish law, could now be processed with a series of machines that promised huge savings of time and money. As town after town adopted these machines, opposition began to rise, until it exploded in 1859 with the publication of “An Alert for Israel,” a collection of letters from prestigious rabbis, who adamantly argued that for anyone interested in following the laws of Passover a matzah made with a machine was no better than a loaf of bread.
The arguments for this position were many, but all will sound familiar to anyone following the AI conversation. Like today, some objected to the machines just because they were new and different, but most had more specific concerns. First, there was the matter of lost jobs. In many parts of Europe matzah was made by the poorest members of society, who were given the job as a way to help them raise money before one of the most cost-intensive holidays of the year. Ceding this job to machines would take work from those who could least afford it.

Beyond economics, there was concern that the machines just weren’t as reliable as people, especially given the rules around matzah-making outlined in Jewish law. What if bits of dough got trapped in the gears, quietly leavening for hours and unknowingly ruining whole batches of matzah in the process? What if the trays warmed the dough too fast? Without proper oversight, how could you trust your own food?
Finally, some objected to the loss of a literal human touch. Jewish law stated that matzah was supposed to be made by people who knew they were baking matzah. A machine, no matter how sophisticated, didn’t “know” anything. How could you eat matzah on Passover knowing that this most important food was made by a mindless machine?
The responses didn’t take long to arrive. “A Cancellation of the Alert,” a collection published the very same yearr, forcefully argued that machine matzah was perfectly fine — and possibly even better than the human product. No, inventions aren’t inherently bad. No, the machines wouldn’t harm the poor, because the machines made matzah less expensive for everyone. No, the machines weren’t prone to error — and they certainly weren’t more error-prone than lazy, careless humans. No, the machines didn’t know what they were doing — but the people who built them did, and wasn’t that enough?
The machines eventually won, but then something happened that I don’t think either side anticipated. With Manichewitz’s machine matzahs claiming most of the American market by the early 20th century, it was now the handmade matzah makers who were on the back foot; it was they and not the machines who needed to demonstrate that they were up to the difficult task of preparing this food with the efficiency and reliability of the machines.
The result is more than a little tragic. Matzah is the Jewish food with the deepest origins of all — deeper than brisket, deeper than latkes, deeper even than challah — and yet it is the ritual food most likely to be picked up at the supermarket and least likely to be made at home. While there are still communities today that exclusively eat handmade matzah, even this job is now largely outsourced to just a few companies that resemble their machine-driven counterparts in scale. While teachers will sometimes demonstrate how to make matzah for educational purposes, across the religious spectrum the era of locally made matzah is over.
Despite the fact that it’s hard to imagine a simpler baked good — matzah is just flour and water, and it’s literally illegal to spend more than 18 minutes making it — its production is treated as though it is only slightly less complicated than constructing a jet engine, and people are worried about shortages as though matzah were a natural resource or an advanced microchip. The transition has been so complete that we barely remember there was a transition at all.

Did the rabbis pushing for machine matzah know this was going to happen? Almost certainly not. The economic impact of machine labor is relatively easy to predict, but the psychological and cultural effects are a lot harder. There was probably no way of knowing how machines would change the way we thought about matzah in the long run, but today it’s clear that automating this ancient task has changed our own relationship to Passover’s central food — and because the change has resulted in a lot of alienation from matzah production, I’m not so sure it was a change for the better. Making matzah locally could have been a way to feel connected to the ancient Israelites, who left Egypt so fast that they didn’t have time to make anything else. Instead of emulating this ad-hoc food, we optimized it for cost and efficiency, in the process turning matzah into just another specialty cracker on the grocery store shelf. Was it really worth it?
It’s probably a bit much to say that OpenAI is just a modern Manischewitz, but the parallels between the debate about machine-generated matzah and the present debate about machine-generated everything are useful for considering how short-term policy choices around AI won’t necessarily capture all of the technology’s long-term effects on how human beings want to spend their time. When we relinquish an activity to an AI for economic reasons, we may eventually come to believe that humans are no longer qualified to do the task at all.
Then as now we must balance our economic needs against our ideas about what kinds of activities make for a good and fulfilling life.

This isn’t Mark Ruffalo’s first antisemitism controversy
Mark Ruffalo is in the spotlight after facing accusations of antisemitism for his criticism of the Ellison family — but this isn’t the first time the actor has been caught in controversy on this topic.
Last Friday, the actor connected the merger of David Ellison’s Paramount with Warner Bros. Discovery to Israel’s war with Hamas. He called Larry Ellison an “oligarch” due to his financial backing of his son David’s merger using wealth earned from his time at Oracle, which created technology used by the Israeli military. His statements immediately drew criticism, with Paramount leaders accusing Ruffalo of invoking antisemitic tropes.
Ruffalo, a four-time Academy Awards nominee best known for playing the Hulk in Marvel movies, has long been an outspoken advocate for progressive causes — including the Palestinian one.
In 2014, Ruffalo made his first public statements about the Israeli-Palestinian conflict, posting criticisms of Israel’s Operation Protective Edge military operation against Hamas.
He criticized Israel for striking Gaza’s el-Wafa hospital, writing that, “Sorry, I thought blowing up Hospitals [sic] was something that all human beings could agree was off limits.”
Ruffalo also questioned the claim that Hamas used civilians as “human shields.”
“Do you honestly think these people, these fellow human beings, would use their own children as shields?” he wrote. “Use your heart.”
Around the same time, Ruffalo also disputed whether Hamas had actually kidnapped three Israeli teenagers, one of the incidents that sparked the 2014 hostilities — an incident that the terrorist group later admitted to.
Ruffalo received criticism for his posts, but stood by his perspective. “Empathizing w/ Gaza does NOT make me anti-Semitic, nor pro-Hamas or anti-Israel,” he wrote in 2014. “It makes me human.”
As clashes between Israel and Hamas sprouted up again in 2021, Ruffalo once again took to Twitter to denounce Israel, likening the situation to South Africa and calling “for sanctions to free Palestinians.”
Soon after, Ruffalo wrote another tweet apologizing for his rhetoric.
“I have reflected & wanted to apologize for posts during the recent Israel/Hamas fighting that suggested Israel is committing ‘genocide,’” he wrote. “It’s not accurate, it’s inflammatory, disrespectful & is being used to justify antisemitism here & abroad. Now is the time to avoid hyperbole.”
Following the Hamas-led Oct. 7 attack in 2023 and Israel’s military response, Ruffalo returned to pro-Palestinian activism. Less than two weeks after the attack, on Oct. 20, Ruffalo — along with more than 50 others creatives through the organization Artists for Ceasefire — sent a letter to President Joe Biden demanding an immediate ceasefire in Gaza. At the following Academy awards, Ruffalo wore a pin from the organization.
In Sept. 2025, Ruffalo, and along with more than 5,500 others in the film industry, signed a letter pledging to boycott “Israeli film institutions” that they believed were “implicated in genocide and apartheid against the Palestinian people.”
Ruffalo has publicly aligned himself with the Boycott Divest Sanction (BDS) movement, calling to “boycott, divest, sanction and prosecute” Israel, on a podcast with Mehdi Hasan. During the same interview, he said that he has stopped talking to former friends who don’t agree with his perspective on the issue.
“I can’t talk to them anymore,” he said. “They’re either trying to convince me that the Palestinian people are all terrorists and they all deserve to die, or in the same breath will tell me that they’re actually human shields, and they deserve to die because they’re human shields.”
Now, after making statements connecting the Paramount-Discovery merger to Israeli military technology, Ruffalo has been accused of antisemitism by numerous Jewish organizations including the Anti-Defamation League and the Simon Weisenthal Center.
The actor has now taken to social media to denounce the accusations of antisemitism, calling the accusation “appalling and fundamentally dishonest,” and saying that criticizing “the actions of the Israeli prime minister, a military technology contract, or the executives who supply it is not the same as criticising Jewish people.”
He added, “Everything I know about acting, activism, and humanism has been profoundly shaped by the Jewish friends, colleagues, and loved ones who have been integral and family throughout every point of my life.”

American synagogues are spending more than ever on security. How much is enough?
At Temple Israel in Bloomfield, Michigan, which was attacked in March by a gunman, getting ready for the High Holidays this year means more than preparing for crowds of worshippers.
The synagogue is spending millions of dollars on security upgrades, including a new gatehouse, artificial intelligence technology and physical and ballistic hardening of its building.
“There are major changes coming,” Rabbi Josh Bennett of Temple Israel said in an interview. “I think that extends then to many of the other places of worship in town, and then, by extension, the entire Jewish community around the country.”
But as congregations install barriers, hire guards and tighten access to their buildings, Jewish leaders are struggling to balance budgets and keep their synagogues welcoming.
Bennett fears fortressing the Jewish community through ever-expanding security upgrades is “unsustainable at all levels,” from the emotional to the financial.
The Secure Community Network, a Jewish security organization that provides threat intelligence and safety training to Jewish institutions across the country, told the Forward that the American Jewish community now spends between $765 million and $1 billion annually on security and safety.
CEO Michael G. Masters said that figure is dramatically higher than it was several years ago, when it was the exception, rather than the rule, for a Jewish institution to have a security plan, let alone layers of cameras, guards, and coordination with law enforcement.
The spending reflects what Mitchell Silber, CEO of the Community Security Initiative, a New York-focused Jewish counterterrorism and security organization, described as “the most complicated threat picture that the Jewish community in the United States has ever faced.”
According to the FBI, Jews were the victims of nearly two-thirds of religion-based hate crimes in the United States in 2025. And these days, Silber’s analysts are tracking threats from white supremacists and neo-Nazis, Islamist extremists and actors inspired by or connected to Iran and Hezbollah, and left-wing violence connected to the Israeli-Palestinian conflict.
“That’s taking a tremendous toll just financially on our Jewish institutions,” Silber said.
The growing costs have pushed Temple Israel to lobby Congress in support of the bipartisan Jewish American Security Act, which would increase federal funding available to protect Jewish institutions. Last week, members of Congress, including the bill’s co-sponsor, Rep. John James of Michigan, visited the Temple to see the security updates.
When congregants help screen for danger
But as congregations pour money into keeping potential attackers out, another question looms: At what point does protecting a synagogue begin to change the experience for those coming in?
“The more you build, there’s, I think, an inverse proportion to how safe people will actually feel when they’re coming in,” said Bennett, whose congregants have been emotionally rattled since the March attack, during which a gunman rammed a truck loaded with gasoline and fireworks into the synagogue. “Nobody wants to walk into a building where you walk by loaded semi-automatic machine guns.”
A person arriving at a synagogue for the first time could have harmful intentions. They could also be new to town, exploring Judaism, or simply looking for a place to spend Shabbat. Distinguishing between those is an important challenge.
Unlike an outside guard, a longtime congregant may know who normally attends services, which unfamiliar face is expected for a wedding or bar mitzvah, and when someone’s behavior genuinely seems out of place. That’s why organizations like SCN and the Community Security Service train community members to serve as additional protection at their own institutions.
In 2026 alone, SCN has conducted close to 1,000 in-person safety trainings, reaching roughly 25,000 people. For the High Holidays, they are offering Zoom Webinars for Jewish institutions across the country, as synagogue-goers who ordinarily recognize most people walking through their doors may suddenly welcome hundreds of unfamiliar worshippers.
Preparation was put to the test at Central Synagogue in Manhattan last Friday, when a man stormed the temple, punched a congregant, and headbutted and spat on a security guard while directing a racial slur at him.
Silber described the response as a “tactical success.”
“Their security team had drilled. Their clergy and staff had drilled. And when the moment came, within less than 60 seconds, they had this individual moved outside of the sanctuary.”
At Temple Israel, the congregation has been fundraising specifically for security. After the March attack, Bennett said, some congregants would like to see “a moat and a full army around our buildings.”
He understands the impulse. But he worries there may be no end to what a synagogue can spend in pursuit of safety.
“How do you do this with the knowledge that it’s financially unsustainable?” Bennett said. “This is not the way we should be spending dollars.”

The far right is more dangerous to Jews than the far left. A historian explains why.
When Jewish leaders speak out these days, it’s often to blast the anti-Israel actions of one Democratic Socialists of America politician or another. Given all the attention — and the millions of dollars raised within the Jewish community to help defeat these candidates — you’d think the greatest existential threat to American Jews was coming from the left.
But a new book by historian Steven Ross is here to tell you: You’d be mistaken.
“What you’ve seen seeping in on the far left is more anti-Israel and some antisemitism,” Ross told me in a phone interview. “But here’s the thing: the left has never called for death to people, the right has.”
Right-wing extremist groups have spent 80 years calling for the death and deportation of Jews and minorities — and sometimes acting upon those calls. The far left, whatever its failures on antisemitism, has not. And unlike in previous years, the far right today has found the two things it lacked: a single leader to unite behind, and a technology to reach millions.
In The Secret War Against Hate: American Resistance to Antisemitism and White Supremacy, Ross, a professor of history at University of Southern California, tracks the continuous, noxious activity of hate groups in the United States from the end of World War II to the present day — and the brave and secretive men and women who sought to thwart them.
The book reads like a great suspense novel, except, unfortunately, it’s nonfiction. And its conclusion — spoiler alert — is that the threat is only growing more dangerous.
Uncannily, in his research, Ross found that Jewish leaders predicted as much — in 1945.
Even before the Allies declared victory in Europe, leaders of the Anti-Defamation League, American Jewish Committee and the Anti-Nazi League, who had launched undercover operations to infiltrate and disrupt hate groups, had come to a disturbing conclusion. They could defeat any hate group, even the Ku Klux Klan, unless the disparate groups could one day “communicate on an instantaneous basis,” and unless the far right figured out a way to make it into one of the two mainstream political parties.
“Here we are,” Ross said. “Everything has come true.” Social media has enabled hate groups to communicate and organize at scale, and President Donald Trump’s pardon of the Jan. 6 rioters — direct ideological descendants of the postwar far right, Ross says — was but one example of the Republican flirtation with extremist and violent groups.
Descendants of the ‘Betrayed Generation’
In the early 1940s, Jewish leaders also predicted that when the war ended, antisemitism and racism would increase — despite Americans having just fought a savage battle against prejudice and fascism.
The Greatest Generation also birthed what Ross calls “the Betrayed Generation,” men and women who returned to a changed America in which liberals, Blacks and Jews were mobilizing and upwardly mobile.
“The Founding Fathers, they insisted, had created a nation based on white Christian rule and they would not allow traitors or people of color to change that,” Ross writes.
Groups like the American Nazi Party, the Columbians and the National States Rights Party warned that Jews were behind “race suicide,” plotting to replace white people with non-white immigrants. They accused Jews of being secret Communists and undermining the cause of “America First.”
“I will solve the Jewish problem once and for all,” James Madole, founder of the fascist National Renaissance Party, told a boisterous rally in Manhattan’s Yorkville neighborhood in February 1953. “I will finish the job that Hitler started.”
During this period, there were an estimated 3,114 right-wing organizations and periodicals that reached a combined membership of over 10 million Americans, says Ross.
The groups carried out a series of bombings against synagogues and Black churches that were, Ross writes, “unrelenting, unpredictable, and unnerving.”
How to fight back
J. Edgar Hoover’s FBI, which should have been tracking these groups, was far more concerned with persecuting potential communists. So the ADL, AJC and the ANL fielded undercover agents to infiltrate and disrupt these groups, often at the risk of their lives.
One of them, a 19-year-old Columbia University student named William Goring, rose to the head of the National Renaissance Party’s leadership. In a memo to his handlers, Goring described the far-right members he encountered as “the failures, the lonely,” who feel “abandoned by their government and gain a strong internal feeling of camaraderie” from the far-right parties.
“To ease their lack of self-respect they make up excuses and find scapegoats. Some fix upon the Jews, others on the Blacks,” Goring wrote.
By the 1970s, this spy network as well as internal strife had weakened these hate groups, their memberships dwindling to hundreds.
Jewish groups “thought they had won the battle against hate,” wrote Ross, and turned their attention to the causes of civil rights and Israel.
But the ideology and organizations festered and regrouped, manifesting in the anti-government militia movement, the white supremacist march in Charlottesville and the Jan. 6 riots. Between 2008 and 2016, the number of militia and anti-government groups rose to 1,400.
Media personalities with millions of followers, like Tucker Carlson and Candace Owens, push warnings against shadowy Jewish influence and the “great replacement theory,” the new term for “race suicide.”
The bombings that wracked Jewish communities in the postwar period have declined, Ross acknowledged. What’s replaced them is a constant stream of hate pushed into people’s social media feeds. Social media has made it harder to infiltrate and disrupt hate networks, while making it easier to constantly find new recruits.
“You don’t have to bodily harm someone,” he said. “Creating a life where they’re afraid, whether it’s Muslim, Jew, immigrant — that’s terrorism, that’s domestic terrorism.”
Meanwhile, Trump and others in his administration openly engage with Holocaust deniers and antisemites. In Florida’s Republican primary races earlier this month, two candidates, Dan Bilzerian and Jake Lang, spouted raw antisemitism. Bilzerian, who lost to a Jewish congressman, had asked his 30 million online followers if Hitler “was a good person.”
Ross, whose father survived the Warsaw Ghetto and Dachau and whose mother survived Auschwitz, said he believes the answer is better education, but that’s “long term.”
I asked him what the short-term solution is.
“Take two people to the polls,” he said. “Get two people in their young 20s who aren’t used to voting, and get them out to the polls. That will change things right now.”
Bilzerian lost badly, but he’s not going away, and neither is the ability to infect minds and harvest hate. The question isn’t whether the far right is more dangerous — Ross has answered that. It’s whether we’re paying attention.
