I think the recent work from home hysteria is a fallacy. Conceptually, working from home has NOTHING to due with covid 19. If it’s so awesome, why wasn’t it adapted en mass years ago? Yahoo a couple years back even rolled back WFH. It’s a trend that will have some effect yes, but it’s being way over hyped. For two main reasons: 1- I’m not sure it will really provide long term benefits to the tech firms jumping on the bandwagon now 2- I’m not sure how many employees will ultimately like it, after the forced-Covid-novelty wears off. i.e. it’s hard to get all those cool tech co benefits like free gourmet food, gyms, awesome office spaces, etc., etc. piped over a zoom meeting ;)
As for WFH effect on the Bay Area, keep in mind that when people work from home, their direct environment becomes MORE, not less important. Would you rather be home based in the Bay Area with tons of things to do nearby, good weather, lots of nature, etc. or someplace with little culture, extreme temperatures, bland immediate environment, etc., etc. There is a reason many people, who can afford to do so, aspire to live in CA and especially the Bay Area. Working from home isn’t going to radically change those aspirations.
