Tens of millions of American jobs could be eliminated by automation in the near future, and New York City Mayor Bill de Blasio says it’s foolish to let the source of that disruption — the technology companies pushing advanced robots and artificial intelligence — also position themselves as the solution.

“I’ve talked to lots of technologists and ... for some, technology becomes a quasi-religion and sort of the answer to all problems,” he said on the latest episode of Recode Decode with Kara Swisher. “But then when you say, what about the workers? What about the people? A silence descends in the room and what many of them cling to is UBI as their get-out-of-jail-free card.”

UBI refers to “universal basic income,” a proposed policy wherein the US government would send no-strings-attached money to all American adults, in the hope that it will relieve their financial pressures and make working in the gig economy a livable career path. Silicon Valley entrepreneur Andrew Yang (who, like de Blasio, is running to be the Democratic nominee for president in 2020) has popularized UBI throughout the campaign, suggesting that every American receive $1,000 from the government every month.

De Blasio praised Yang’s recognition that job automation poses a serious threat to workers in several industries, but said that $1,000 “couldn’t even come close to being enough.”

“Give me a break,” he said. “Looking at the cost of living in so much of America, that is not even close to what people need. Second of all, hey, what happens if the government decides to stop sending you the check? What happens if there’s a recession? What happens if there’s a political crisis? You are screwed. And so it immediately falls apart.”

“UBI could be part of a[n] answer to the challenge of automation and potentially tens of millions of people that work,” de Blasio added. “It is a false idol if you say, ‘Oh, this will solve the problem.’ ... That’s ridiculous. That’s dangerous.”

On the new podcast, de Blasio also endorsed a tougher antitrust stance against tech giants, such as Google and Facebook, comparing them to the oil and railroad companies that America’s monopoly laws were originally designed to combat: All three industries provide valuable services to customers, but their susceptibility to greed and exploitation means they need “ground rules.”

“We have societally always recognized, when we’ve gone into a new reality, that we better put some rules on,” he said. “The problem here has been this strange overindulgence in the notion of, ‘Well, technology is simply good and the intentions are pure and it’s liberating us.’”

“There’s a form of propaganda here,” de Blasio added. “It’s like everything else human: There’s good things in it. There’s dangers in it. I don’t trust any company. They’re still multinational corporations. ... The government is imperfect, but at least it comes with a democratic mandate and some checks and balances and some transparency. We better get the hell in this.”
