Nah, people say they will quit , but they wont, there are people who do want to go back to the office, and will die to work at Google, also very competent (not as much as people here that love working from home, I'm sure). Also most tech companies will go back, MSFT, Amazon, ... You can go to FB tho, but then you will be working for FB, if you care only about the money, then is fine I guess, at least personally is not a place I would love to be in.
