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.

A comedian went viral for saying he supports Israel onstage — he wasn’t even there
Menachem Silverstein’s High Holidays were interrupted by what he calls a beautifully ironic “monkey paw situation.”
“Like any good Jewish comedian, I’m in Rosh Hashanah services praying to God for a little bit of a boost in my career, for something to go viral, for something to hit,” Silverstein, a 30-year-old comic in Los Angeles, told me. “I turn my phone after hag. I have about 40-plus messages from people being like, ‘What the hell’s happening? Is this you?’”
Friends were sending him links to a video of a crowd leaving a theater in the middle of a standup set. The caption overlaid on the clip said, in English and Arabic, “audience walks out after comedian backs Israel.” On an X post with more than 2 million views, an account named “Truthseeker” identified the comic as Silverstein.
Silverstein knew immediately the video was of the Laugh Factory in Chicago, a venue he last played this summer. He had no memory of the crowd walking out — a traumatic experience for any standup. In fact, as he took a closer look at the video, he realized it wasn’t even him onstage.
“My most viral thing was not showing up to a comedy club, which is hilarious in itself,” said Silverstein, who estimates across platforms the clip has been seen more than 10 million times. “If I would have known, I would have missed more shows.”
By the time Silverstein was clued into his virality, it was too late to contain the disinformation.
Alex Jones picked the clip up, commenting, “It’s got one guy in a yarmulke. He literally says, ‘If you don’t support what Israel is doing in this war, leave.’”
No such statement is made in the clip. There’s no guy in a yarmulke, only a man in a dark t-shirt who appears to be blindfolded. This didn’t stop news outlets like Palestine Chronicle and the 1.1 million follower Global Reports Instagram account from running with the story.
Someone captioned the original clip — now deleted — indicating the comedian stated their support for Israel, leading to a mass exodus. From there, Truthseeker identified Silverstein as the comic, based, Silverstein believes, on a joke he retired about three years ago.
“Basically, the joke was, ‘Hi, my name is Menachem. I stand with Israel. It’s not political; they’re just the only people that can pronounce my name.’”
Grok and other AI models reinforced the claim that Silverstein was the person in the clip. But the real reason for everyone leaving their seats was something much less loaded: a prank.
David Fuhrer, president of the Laugh Factory said, based on an account confirmed by the Chicago Laugh Factory’s head of operations, that the video was from a Sept. 10 performance of a regular show called “What Could Go Wrong?,” in which practical jokes are played on comics.
“In this particular case, we had a comedian named Kieron Harrell and we blindfolded him and put headphones on him,” Fuhrer said. “They walked the entire audience out into the lobby as a joke so he had an empty room he was performing to.”
Fuhrer said it had “nothing to do with antisemitism or people walking out on Menachem.” He doesn’t know who repurposed the video, only that it had gone viral.
“It’s a shame because he’s a wonderful person and a great performer and a part of our family here.”
If you go to the “What Could Go Wrong?” Instagram, you’ll see a better image of the real comic, Harrell, who looks nothing like Silverstein.
Daniel Cassilagio, who produces “What Could Go Wrong,” captioned the images of the performer, saying the show was “so good that it was used as a geo political [sic] disinformation campaign.”
Cassilagio wrote on Instagram that the clip was recorded, uploaded without the producers’ knowledge and “then virally shared by what are most likely bots from China.”
People who don’t check their sources have “been harassing both the comic that was on stage, and a comic from LA who I’ve never even heard about or met,” Cassilagio wrote on a post that, judging by its 166 likes, has far less visibility than the fake account. “He wasn’t even in Chicago at the time.”
Silverstein told me that, while he added around 200 followers, he’s been inundated with hateful comments and his reach has dropped as people have been reporting his account. If you search his name now, the top hits are for his nonexistent scandal. When he’s looking to play clubs, he’s concerned that bookers will see he “walked a crowd” and deny him a slot.
Beyond the made-up controversy, there’s not much about geopolitics in Silverstein’s act. His material includes jokes on fatherhood, being 5’9” (“a Jewish 6’2”) and some well-deserved ribbing of Kanye West. In videos, he can be seen circumcising a baby carrot.
In an age when performers like Macklemore and Jerry Seinfeld have been canceled for their views on Israel and Palestinians, Silverstein sees a new frontier in his experience.
“It used to be you watch a podcast or watch a stand-up clip, clip someone out of context, post it, and get them canceled,” he said. “Now they’re getting away with just posting a random thing, putting your name on it, and then people believe it.”

‘Run, hide, fight’: Synagogues make threat preparedness part of High Holiday services
Rabbi Yosef Kanefsky plans to open his Yom Kippur sermon this year in an unusual way: with an emergency evacuation plan.
It’s how he opened his Rosh Hashanah sermon, too.
“I mentioned [that] people should understand where the exits are,” Kanefsky said. “I mentioned what our plan is, God forbid, if we need to evacuate the children in the youth program — that we have volunteers for that.”
Kanefsky, senior rabbi at B’nai David-Judea Congregation in Los Angeles, acknowledged that the reminder to prepare for the worst could be “potentially a little bit jarring” on the holiest days of the year. But with synagogues on heightened alert, he said, it felt unfortunately necessary.
“It’s just part of our lives right now,” he said. “That extra measure of vigilance.”
Extra security measures at synagogues are nothing new. Since the 2018 shooting that killed 11 worshippers at Pittsburgh’s Tree of Life synagogue, Jewish institutions have invested heavily in infrastructure, personnel and training to counter the threat of violence. But this High Holiday season, several synagogues are taking the unusual step of integrating emergency preparedness into the services themselves, whether through verbal instructions like Kanefsky’s or written plans handed out alongside prayer books.
A flyer distributed at Beth Tzedec Congregation in Toronto outlines a three-point plan in the event of an attack: Run, hide or — as a last resort — “Be prepared to defend yourself.”
“Remember: Your actions before police arrive may save your life,” it reads in all-caps.
In August, the Jewish nonprofit Secure Community Network released a safety card that synagogues can customize with their own evacuation maps then place in their pews. While a range of scenarios could prompt a building evacuation, like a fire or earthquake, the card focuses on reacting to an attack.
It includes instructions for how to make a tourniquet to stop bleeding and tips for fleeing or fighting “the shooter.”
And at Congregation Emanu-El in San Francisco, a flyer advising congregants to run, hide, or fight in the event of an attack was placed on every other seatback during Rosh Hashanah.
“It brought home the potential dangers in a way I hadn’t seen before,” Frances Dinkelspiel, a member of Congregation Emanu-El, told the Forward. “You’re going in for services. You’re opening your heart. There’s a sense of community. You’re embracing one another. And then there’s this piece of paper that’s reminding you: Don’t relax too much.”
Kanefsky said he felt a responsibility to his congregation to provide safety instructions, noting that the High Holidays may attract out-of-town visitors unfamiliar with the building.
But he also acknowledged that such warnings “can take away from the spiritual mood that we’re working so hard on building,” he said.
Kanefsky said he tried to make the announcement as unobtrusive as possible — giving the instructions in what he called “a spiritual and emotional envelope” by thanking the synagogue’s security team and framing preparedness as “part of the devotion to one another and our devotion to God.”
Michael Masters, Secure Community Network’s CEO, said the High Holidays present an elevated security risk at synagogues compared with other times of year. Even basic preparedness measures, like knowing where the exits are, can make a meaningful difference in a threat situation, he said.
He cited the ramming attack on Temple Israel in West Bloomfield, Michigan, in March as a prominent recent example. Seconds after the assailant drove a truck filled with explosives through a building entrance, a security guard opened fire on the vehicle; after the vehicle caught fire, the campus was safely evacuated.
“The guard was there, and he was well trained, and he did an amazing job, as did law enforcement,” Masters said. “But the faculty and the staff and the students were all trained as well.”
Dinkelspiel emphasized that she feels safe at her synagogue, which has a modern security system and bollards around the sidewalk to prevent cars from driving onto the property. But that sense of safety, she said, was part of what made the flyer so unnerving.
“After all these security measures the congregation has,” Dinkelspiel said, “there was still this reminder on this flimsy piece of paper that Jews can be attacked at any time.”

Mamdani once vowed to arrest Netanyahu. Now he won’t join protests against him.
New York City Mayor Zohran Mamdani said Wednesday that he will not join protests against Israeli Prime Minister Benjamin Netanyahu when he arrives in the city to address the United Nations annual gathering next week and pushed back on the suggestion that he ever encouraged New Yorkers to protest the Israeli leader.
“I do not have any plans to attend any protest at the U.N. General Assembly,” Mamdani told reporters. “To New Yorkers, I have never encouraged them to protest. What I have always told them is that they have the right to do so in the city.”
But two months ago, when Mamdani was asked what New Yorkers frustrated with Netanyahu should do when the Israeli leader came to the city for the annual fall U.N. event, the mayor repeatedly pointed to protest as an option. “I think one of the bedrocks of our city is protest,” Mamdani said at a July 22 press conference. “It is something that has been a part of what makes our city so special: that New Yorkers can express themselves, whether they are in support or in opposition, no matter the topic.”
Mamdani’s July remarks came after a legal review the mayor ordered concluded that he lacks the power to order the arrest of Netanyahu, a pledge he made during his mayoral election campaign.
In July, when a reporter followed up directly, “Are you urging them to protest?” Mamdani stopped short of saying yes. But he again pointed to protests as a way for New Yorkers who oppose Netanyahu to make their voices heard. “I’m simply saying that this is a city where — if anyone feels a level of frustration or opposition, protest is something that we will always respect,” Mamdani said. “I leave it to New Yorkers themselves to make that decision,” he added.
From arrest pledge to protest rights
Mamdani had campaigned on ordering Netanyahu’s arrest based on a warrant issued by the International Criminal Court in November 2024, which accused the Israeli prime minister, former Israeli Defense Minister Yoav Gallant and Hamas military commander Mohammed Deif of war crimes and crimes against humanity. Netanyahu has rejected the charges. The United States is not a member of the International Criminal Court and the Trump administration imposed sanctions on the ICC months after it issued the warrants.
After taking office, Mamdani ordered a legal review and acknowledged in July that New York City does not have the authority to execute the ICC warrant.
He made that announcement in an unusual video address describing Netanyahu as “a war criminal, the architect of a horrific genocide against the Palestinian people” and declared that the Israeli leader would not be welcome in New York, home to the largest concentration of Jews in the United States.
The address drew criticism from Jewish leaders who questioned why the mayor was devoting so much attention to an arrest he acknowledged he could not legally carry out. The criticism came amid growing tension between Mamdani and parts of New York’s Jewish community over his rhetoric about Israel. Jewish organizations have also raised concerns about it contributing to a hostile climate for Jews across the city.
It was against that backdrop that Mamdani was pressed at the July press conference about what he would tell Palestinian supporters who had welcomed his promise to arrest Netanyahu, and were disappointed that he could not fulfill it. That is when he turned to protest as a remaining option. “I want to make it very clear that that welcome ends with me,” Mamdani said. “ I will not be welcoming Benjamin Netanyahu or any other war criminals when they come to this city.”
Netanyahu is expected to arrive in New York City next Wednesday under heavy security measures and address the U.N. General Assembly on Thursday before returning to Israel. One Israeli media outlet reported that the official plane carrying the Israeli leader, known as “Wings of Zion,” will land at Newark International Airport in New Jersey instead of John F. Kennedy International Airport in New York due to concerns that Mamdani could try to prevent the aircraft from remaining parked at JFK during Netanyahu’s visit.
Protests against Netanyahu are planned outside his hotel and near the United Nations during his address. Jewish groups are also planning a mass rally against antisemitism on Wednesday.
At Wednesday’s press conference, Mamdani drew a sharper distinction between encouraging protests and defending the right to hold them. “We respect that right,” he said. “And this is a city that is proud of the Constitution, proud of the First Amendment; we’ll continue to do so.”
Mamdani cited the same First Amendment right when asked about students from Ramaz and SAR, two prominent Modern Orthodox schools, who are planning a prayer vigil outside the mayor’s residence on Friday morning in support of Israel. “They can have a vigil, or I’ve heard some describe it even as a ‘protest,’” he said. “Whatever it is intended to be, they have the room and space to do so outside of Gracie Mansion. Though, he added, he would “probably be somewhere else across the city” when they gather.
