Michael Seibel, who leads startup incubator and investment firm Y Combinator, advised more than 2,000 engineering students gathered for an app-building competition at University of California, Berkeley, to avoid jobs in big tech. “The worst thing that can happen to you is you get a job at Google,” Seibel said. The New York Times said he called those jobs “$100,000-a-year welfare” — meaning, he said, that workers can get tethered to the paycheck and avoid taking risks.
