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.

London Police Set Up Specialist Jewish Protection Team

British police are setting up a new team of 100 officers including counter terrorism specialists to help protect Jewish communities across London after a series of antisemitic attacks including the stabbing of two men.
The plan announced on Wednesday for a dedicated protection team comes as officers announced more arrests for antisemitism, including detaining a 35-year-old man on Saturday after rocks were thrown at an ambulance belonging to the Jewish community.
London‘s top police boss Mark Rowley said Jewish communities were facing “sustained threats” from hostile state actors as well as extreme right-wing groups, elements of the extreme left, and Islamist terrorists.
Detectives are examining whether the arson incidents have possible Iranian links, after British security officials warned that Iran was using criminal proxies to carry out hostile activity.
Since late March, there have been a number of high-profile arson attacks with four Jewish ambulances burned and synagogues targeted. Last week, two Jewish men were also stabbed. Both victims survived the attack.
Over the past four weeks, police said they had arrested around 50 people for antisemitic hate crimes and charged eight individuals. On top of that, 28 arrests have been made as part of investigations alongside counter terrorism policing for arson and other serious incidents.
“This new team will be primarily focused on protecting the Jewish community, which faces some of the highest levels of hate crime alongside significant terrorist and hostile state threats,” said a statement from London‘s Metropolitan Police force.
British Prime Minister Keir Starmer convened a meeting on Monday with business, health and cultural leaders aimed at trying to tackle antisemitism.

Iran Reviewing US Proposal to End War, Though Key Demands Remain Unaddressed

Iran said on Wednesday it was reviewing a US peace proposal that sources said would formally end the war while leaving unresolved the key US demands that Iran suspend its nuclear program and reopen the Strait of Hormuz.
An Iranian foreign ministry spokesperson cited by Iran‘s ISNA news agency said Tehran would convey its response. US President Donald Trump said he believed Iran wanted an agreement.
“They want to make a deal. We’ve had very good talks over the last 24 hours, and it’s very possible that we’ll make a deal,” Trump told reporters in the Oval Office on Wednesday.
Earlier in the day, Trump had sounded more pessimistic about the chances of a deal. In a Truth Social post, he threatened to restart the US bombing campaign in Iran, calling the possibility of Tehran agreeing to the latest US proposal a “big assumption.”
Trump has repeatedly played up the prospect of an agreement that would end the war that started Feb. 28, so far without success. The two sides remain at odds over a variety of difficult issues, such as Iran‘s nuclear ambitions and its control of the Strait of Hormuz, which before the war handled one-fifth of the world’s oil and gas supply.
A Pakistani source and another source briefed on the mediation said an agreement was close on a one-page memorandum that would formally end the conflict. That would kick off discussions to unblock shipping through the strait, lift US sanctions on Iran, and set curbs on Iran‘s nuclear program, the sources said.
It was unclear how the memorandum differs from a 14-point plan proposed by Iran last week, and Iran has yet to respond to the latest US proposal.
Iran‘s semi-official Tasnim news agency, citing an unnamed source, said the US proposal contained some unacceptable provisions, without specifying which ones.
Iranian lawmaker Ebrahim Rezaei, a spokesperson for parliament’s powerful foreign policy and national security committee, described the text as “more of an American wish-list than a reality.”
“The Americans will not gain anything in a war they are losing that they have not gained in face-to-face negotiations,” he wrote on social media.
OIL PRICES TUMBLE
Reports of a possible agreement caused global oil prices to tumble to two-week lows, with benchmark Brent crude futures falling around 11% to around $98 a barrel at one point before rising back above the $100 mark.
Global share prices also leapt and bond yields fell on optimism about an end to a war that has disrupted energy supplies.
Trump on Tuesday paused a two-day-old naval mission to reopen the blockaded strait, citing progress in peace talks.
The US military has kept up its own blockade on Iranian ships in the region. US Central Command said forces fired at an unladen Iranian-flagged tanker on Wednesday, disabling the vessel as it attempted to sail toward an Iranian port in violation of the blockade.
NO MENTION OF KEY US DEMANDS
The source briefed on the mediation said the US negotiations were being led by Trump’s envoy Steve Witkoff and son-in-law Jared Kushner. If both sides agreed on the preliminary deal, that would start the clock on 30 days of detailed negotiations to reach a full agreement.
The full agreement would end the competing US and Iranian blockades on the strait, lift US sanctions, and release frozen Iranian funds. It would also include some curbs on Iran‘s nuclear program, with the aim of a pause or moratorium on Iranian enrichment of uranium.
While the sources said the memorandum would not initially require concessions from either side, they did not mention several key demands Washington has made in the past, which Iran has rejected, such as curbs on Iran‘s missile program and an end to its support for proxy militias in the Middle East.
The sources also made no mention of Iran‘s existing stockpile of more than 400 kg (900 pounds) of near-weapons-grade uranium.
Israeli Prime Minister Benjamin Netanyahu, Trump’s ally against Iran, said on Wednesday the two leaders agreed that all enriched uranium must be removed from Iran to prevent it from developing a nuclear bomb.
Tehran denies wanting to acquire a nuclear weapon.

Brussels cathedral installs plaques apologizing for medieval antisemitic persecution depicted in stained glass
(JTA) — More than 650 years after Jews in Brussels were executed and expelled following false antisemitic accusations, church officials at the Cathedral of St. Michael and St. Gudula have installed a plaque apologizing for the persecution commemorated in its stained glass windows.
At a ceremony on April 27, Archbishop Luc Terlinden of Mechelen-Brussels and Rabbi Albert Guigui, the chief rabbi of Brussels, unveiled four plaques, written in Dutch, French, English and Hebrew, providing historical context for the windows and an apology for the antisemitic persecution tied to the events they depict.
The plaques, which Terlinden signed, state that “baseless accusations of the desecration of the Eucharistic host were made against Jewish communities” in medieval Europe and that the accusations “led to persecution, massacres, and unjustifiable expulsions.” The windows show Jews being executed at the stake in response to their alleged attacks on the Eucharist, bread that Catholic doctrine considers a literal representation of Jesus’ body.
“Theological and social anti-Judaism is in direct contradiction with the Gospel of Christ, which calls for truth, justice, and brotherhood,” the plaques say. “We ask forgiveness from the Jewish people for the suffering these accusations have caused.”
The stained glass windows in the cathedral depict the “Brussels Host Desecration,” an antisemitic accusation in 1370 that Jews had desecrated communion wafers, leading to the execution of Jews in Brussels and the expulsion of the city’s Jewish community.
The windows have drawn scrutiny for decades, particularly as the Catholic Church sought to reckon with its history of antisemitism. In 1969, shortly after the landmark Nostra Aetate declaration rejecting longstanding anti-Jewish Catholic doctrine, the Archbishop of Brussels ordered that several paintings be removed and a plaque be mounted to offer context about the remaining depictions.
Several years later, the European Jewish Congress noted last week, Catholic leaders did install a plaque that drew readers’ attention to “the biased nature of the accusations [against the Jews accused of the desecration] and to the legendary presentation of the ‘miracle.’”
But Flora Cassen, the director of the Brandeis Center for Jewish Studies and a scholar of European antisemitism, said the existing plaque was “very ambiguous about the responsibility and what happened” and installed in an easy-to-miss location. The new plaques, she said, contain a clear and “very moving” apology and cannot be missed by anyone who comes to see the windows.
“The significance is enormous of the church finally putting a plaque there that tells the story, that acknowledges the antisemitism behind it, that acknowledges that it was a slander and that it resulted in persecution and in the execution of Jews in Brussels and their expulsion,” Cassen said.
The new plaques cite Nostra Aetate and the Catholic Church’s subsequent effort under Pope John Paul II to reckon with historical antisemitism in 2000. They affirm the church’s “commitment to combat all forms of antisemitism, to deepen dialogue between Jews and Christians, and to pass on to future generations a clear remembrance, based on the acknowledgement of truth and mutual respect.”
While some have called for the historic windows to be removed, Guigui said in a statement that the plaques represented an appropriate way to address relics of historical antisemitism.
“What matters today is how we look at these images,” the rabbi said. “They must not be erased, because they are part of history, but they must be accompanied by explanation and moral insight in order to understand the context and avoid repeating past mistakes.”
