Sure, pick a tech niche or main area and I name you some specific examples. But as this is a financial website let me start with Bloomberg and Refinitiv. I know tons of managers, quants, and front line people there and pretty much every tech heavy project in both firms has come to an entire halt. All hands on deck to keep the core business running, not much else. Both firms are excellent examples because both pride themselves as being able to continue functioning with nobody in the office and everyone working from home. Yeah, the companies are kept afloat but not much else is happening right now at all. Especially Bloomberg usually is incredibly innovative on the technology side.
And the claim by another poster that remote work has been going on for ages is not true. Why do you think until very recently SF real estate prices have been out of any proportion? Because tech workers were kept on the various campuses to work in person. If remote work worked so well then Google and MSFT and many others would have sent all their workers home for the past 15 years. They have not by large majority. I believe the reason is that humans need social interaction other than the spouse and neighbor to be motivated, efficient, and productive. Every psychologist knows that. And let's all please cut the crap to use some anecdotal evidence of some small business nobody has ever heard of and nothing is verifiable. I named the two largest financial data and tech firms in the world and some of the largest software houses. Show me how a majority of Google or MSFT employees worked remotely before the crisis and we can talk. Who are all those highly paid people in the bay area?
