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.

‘It’s the Jews’: San Diego mosque shooters decried ‘the universal enemy’ in hate-filled manifesto
The two young men who killed three people at a San Diego mosque on Monday published a conspiracy theory-filled manifesto whose primary focus was on Jews, calling them the “universal enemy.”
The manifesto’s contents also suggest they may have had additional plans to target Jewish institutions.
Authorities have identified Cain Lee Clark, 17, and Caleb Liam Vazquez, 18, as the shooters who killed a security guard and two members of the Islamic Center of San Diego. The two livestreamed the attack before both were found dead in a car by apparent suicide, blocks away from the mosque.
The three killed at the mosque were Amin Abdullah, 51, Mansour Kaziha, 78, and Nadir Awad, 57.
Jewish leaders across the country and in San Diego widely condemned the attack.
The 74-page manifesto, which contains a section written by each shooter, reveals a wide-ranging hatred rooted in white Christian nationalist ideas, including Great Replacement Theory, and fueled by the two teenagers’ own social alienation. Among the other groups attacked in the document are Muslims, women, Black people, gay and transgender people, and immigrants.
But the shooters’ deepest resentment seemed reserved for Jewish people.
‘The universal enemy’
The manifesto listed previous antisemitic shootings at the Tree of Life synagogue and Chabad of Poway among the teens’ many sources of inspiration, calling the assailant in the latter incident a “saint.” It called the Jews “the children of Satan.” It denied the Holocaust as a “complete fabrication.” Vazquez called Adolf Hitler his hero; in his section, Clark wrote out the Fourteen Words, a neo-Nazi declaration.
“Everyone has their own idea of who is to blame for all the wrong in the world,” Vazquez wrote in a section titled “The Universal Enemy.”
He printed his answer to the question four times in a row in all capital letters: “It’s the Jews.”
Authorities have said the shooters met online before realizing they both lived in the San Diego area, without specifying the platform where they met.
But the document’s cover pages also provided a clue to their radicalization, bearing the insignia of Atomwaffen Division, a neo-Nazi group that emerged during the first Trump administration.
Atomwaffen members are part of a network of mostly online extremist groups that subscribe to “accelerationism,” the idea that forcing societal collapse through an all-out race war is the only way to restore white supremacy and save civilization. The idea is propounded by a white nationalist named James Mason, author of a book called Siege that both shooters cited.
“Though officially I was not a part of any groups or organizations there are many I support, I would even go so far as to say I did it for Atomwaffen Division, Terrorgram, The Base, and North Korea,” Vazquez wrote.
Atomwaffen members have been convicted in previous antisemitic murders. In 2019, one named Samuel Woodward lured a gay and Jewish college student named Blaze Bernstein to an Orange County park before stabbing him to death. Woodward, who was 20 at the time, is now serving a life sentence, and Atomwaffen fractured into other groups in the years after his arrest.
Secondary targets
Whereas the shooters were unsparing toward Jews in the manifesto, with Vazquez calling them the “most evil creature in the world,” they espoused mixed feelings about Muslims in the document before they killed three. “I don’t hate Muslims, at least not really,” Vazquez wrote. “What I hate is the religion of Islam itself and them invading my country.”
He added that Islam “is completely contradictory to both Western morals and values and Christianity.”
But he wrote only three paragraphs about Islam and Muslims — about one page — before the section ends with the word “unfinished” in brackets.
Clark appeared more committed to the eradication of Islam in his writing. Muslims and Jews, he said, “must be isolated and exterminated.” Yet he, like Vazquez, wrote several pages denigrating Jewish people.
The shooters did not state why they ultimately targeted a mosque. Vazquez wrote their plan was to “cause as much death and destruction” as fast as possible with a “diverse” selection of targets. The document provides lines for listing three separate locations, but none of them are filled out.
“All locations were surveyed and mapped out to the best of our ability,” he wrote.

Rep. Dan Goldman urges ‘no’ vote on proposed Brooklyn Israel boycott, warning of antisemitism
Rep. Dan Goldman of New York and his primary challenger Brad Lander are wading into the contentious debate over a proposed boycott of Israeli products at a Brooklyn cooperative grocery store ahead of an expected vote next week.
In a statement shared exclusively with the Forward on Wednesday, Goldman urged members of the popular Park Slope Food Coop in Brooklyn to attend a May 26 vote and cast ballots against the boycott resolution — and condemned the measure as antisemitic.
“Everyone is free to criticize the Israeli government — which I do not hesitate to do — but joining a movement that was founded on the principle of the elimination of Israel will have no impact on the Israeli government or the Israeli economy,” Goldman said in his statement. “Instead, it only succeeds at shifting the responsibility for the Israeli government’s actions to American Jews — which is quintessential antisemitism.”
Goldman said that he is aligning himself with Rabbi Rachel Timoner of Congregation Beth Elohim, a progressive leader, as the debate has spilled into local politics and Jewish communal life in the progressive neighborhood.
The resolution says the boycott would persist “Until Israel complies with international law, including by ceasing unlawful discriminatory practices, in its treatment of Palestinians.”
Timoner addressed the proposal in her weekly Shabbat sermon earlier this month.
“Many simply want to see the Palestinian people be free and safe and equal, and I do too, but this is not the way,” Timoner said. “This way is wrong.
Calling it a “proxy war” to what has been dividing Americans in recent years over the Israeli-Palestinian conflict, one “that is laced with antisemitism, Timoner said that many members of her congregation — she and herself — would be forced to resign from their co-op membership if the resolution passes.
The rabbi’s sermon reflected the careful line she has tried to walk since the Oct. 7, 2023 Hamas attack and the war in Gaza — openly criticizing Israeli government policies while rejecting the singling out of Israel. In March 2024, Timoner attended for the first time what was then a weekly protest to call for a bilateral ceasefire and hostage deal, one that Lander attended regularly. In her remarks she said that she had held back until then from calling for a ceasefire in Gaza “because it was being used by people who celebrated Oct. 7, people who do not hold Hamas responsible, and people who want to eliminate the state of Israel — and I did not want to be associated with that.”
Timoner is a co-founder and board member of the New York Jewish Agenda, a progressive advocacy group formed in 2020 to be a voice for liberal Jews in New York. Lander is a member of NYJA’s leaders network. A Goldman campaign official noted that the congressman and Timoner have met several times privately to discuss issues affecting the district and that Goldman has attended services at Beth Elohim in the past.
Goldman, the two-term incumbent, challenged his Democratic primary rival to publicly oppose the measure as well, “to stand with our neighbors, and make it clear that this dangerous bigotry has no place in our city.”
Lander, a close ally of New York City Mayor Zohran Mamdani, told the Forward he isn’t a member of the Coop but would vote against the resolution if he were, pointing to Timoner’s sermon. “Principled people can disagree here,” Lander said in a statement that did not take a position on the resolution. “Boycotts, divestments, and sanctions are legitimate tools of advocacy campaigns. Unlike my opponent, I don’t believe all opposition to Israel is antisemitic.”
A long-running boycott fight
The proposal to boycott Israeli products has riven the Brooklyn institution’s roughly 16,000 members. It was introduced in 2024 by a local advocacy group called Park Slope Food Coop Members for Palestine. The resolution would require the Coop to boycott Israeli-made products “until Israel complies with international law in its treatment of Palestinians.”
Coop4Unity, opposing the resolution, is urging shoppers to “bring back cooperation” and “stop polarization.”
The measure is largely symbolic, given that the Coop only carries a handful of items imported from Israel, like EcoLove shampoo and conditioner. At least one, Al Arz tahini, is made by an Israeli Arab in Nazareth. The coop first considered a boycott resolution in 2012.
The debate has grown increasingly heated in recent months, erupting most recently publicly during a general meeting when a member made said “Jewish supremacism is a problem in this country,” a remark that many attendees and Jewish organizations condemned.
The comment — which received applause at the meeting — came during a second resolution that would lower the voting threshold for boycott measures from 75% to 51%.
Goldman strongly condemned the remarks in his statement on Wednesday. “That is not a critique of Israeli policy or advocacy for Palestinian rights,” he said. “It is an old and ugly antisemitic conspiracy theory that fueled the Nazis and then was used by David Duke and the Ku Klux Klan.”
A heated primary over support for Israel
The boycott fight is the latest issue in an already heated primary challenge to Goldman being largely battled over Israel and antisemitism.
Last month, Lander, who has described himself as a liberal Zionist, joined some progressive House members in calling for an end to U.S. aid to Israel. Lander — who described Israel’s actions in Gaza as “genocide” — said he would apply that as well to Israel’s defensive Iron Dome system, high-tech missile interception that protects lives, property and infrastructure against assaults from Iran and allied groups, including Hamas and Hezbollah. Lander said that Israel has the ability to purchase its defense with its own funds.
The 10th Congressional District, which includes Borough Park and Park Slope in Brooklyn as well as parts of lower Manhattan, voted heavily for Mamdani, an outspoken critic of Israel. Mamdani is backing Lander in the primary.
Goldman, an heir to the Levi Strauss fortune and former Trump impeachment prosecutor who was elected in 2022, is aligned with the mainstream positions of national Democrats on Israel: supportive of Israel’s security while finding a pathway for a two-state solution, sharply critical of Prime Minister Benjamin Netanyahu’s right-wing government, and opposed to settlement expansion and settler violence.
Recent polling has shown Goldman trailing Lander in the June 23 primary.
Goldman framed the Coop dispute as about something larger than electoral politics. “It’s time we unite together on this issue,” he said, “and fight for the safe, loving, inclusive community we all deserve.”

Itamar Ben-Gvir draws criticism from Netanyahu for video taunting detained flotilla activists
(JTA) — Prime Minister Benjamin Netanyahu has joined a chorus of Israelis and Jews denouncing his national security minister, Itamar Ben-Gvir, for posting a video that showed Ben-Gvir taunting detained activists from a Gaza-bound aid flotilla that had been intercepted by the Israeli navy.
“Welcome to Israel, we are the masters,” Ben-Gvir said in the video as he waved a large Israeli flag above the detained activists, who could be seen blindfolded and kneeling on the ground with their hands behind their backs.
Roughly 430 activists that took part in the Global Sumud Flotilla, which set sail from Turkey last Thursday, were brought to the city of Ashdod aboard Israeli naval ships on Wednesday, marking the latest in a long-running series of confrontations between Israel and activists seeking to break its naval blockade of Gaza.
In a second video posted on social media, Ben-Gvir said that the activists “came here all full of pride like big heroes. Look at them now,” appealing to Netanyahu to grant him permission to imprison them.

Netanyahu said in a statement that he had instructed authorities to deport the activists “as soon as possible.” But he also offered a public rebuke of Ben-Gvir.
“Israel has every right to prevent provocative flotillas of Hamas terrorist supporters from entering our territorial waters and reaching Gaza,” Netanyahu said. “However, the way that Minister Ben Gvir dealt with the flotilla activists is not in line with Israel’s values and norms.”
The foreign ministers of several countries, including Canada, Spain, France, the Netherlands and Italy, also condemned the videos and summoned their Israeli diplomats to answer for the display.
But some of the sharpest criticism came from within Israel, where Ben-Gvir plays a crucial role in maintaining the governing coalition while also engaging in antics that threaten to flare tensions and undercut the country’s claims that it behaves in accordance with international law.
Ben-Gvir is “not the face of Israel,” tweeted Foreign Minister Gideon Saar in English.
“You knowingly caused harm to our State in this disgraceful display — and not for the first time,” Saar wrote. “You have undone tremendous, professional, and successful efforts made by so many people — from IDF soldiers to Foreign Ministry staff and many others.”
Ben-Gvir’s videos come as his antics and rhetoric have drawn new scrutiny in recent days. Last week, he departed from longstanding norms and waved an Israeli flag on the Temple Mount, a Muslim holy site, in a show of Jewish supremacy. His oversight of Israeli prisons, where he has said he wants to see prisoners given only the minimum of food and comfort as required by law, also drew attention because of a New York Times column alleging sexual abuse of Palestinian prisoners.
Progressive groups heavily criticized Ben-Gvir’s video, saying that it was inappropriate for him to be part of the Israeli government.
“The disgusting images of Israel’s National Security Minister abusing detainees from the Gaza flotilla are not just bad optics,” tweeted Mickey Gitzin, the acting CEO of the New Israel Fund. “A government that gives a Kahanist this kind of power has already abandoned any notion of decency. These grotesque images are the real face of current Israeli policy.”
Ben-Gvir’s videos showing the treatment of participants in the latest flotilla offered a contrast to other recent interceptions in which Israel has released footage appearing to show activists being treated without force. When past arrestees from flotillas have alleged abusive treatment, Israel has denied it.
The organizers of the Global Sumud Flotilla said all of its boats had been intercepted by Israel by Tuesday evening, accusing Israel of employing “illegal, high-seas aggression.” The Israeli Foreign Ministry said no live munition was used during the operation, which it said was necessary because it will “not permit any breach of the lawful naval blockade on Gaza.”
Among the activists aboard the more than 50 boats in the flotilla was the sister of Irish President Catherine Connolly. On Tuesday, Connolly, who was elected in October and has a record of anti-Israel rhetoric, called the detention of Irish activists aboard the flotilla “unacceptable.”
