I miss nice offices though. Before the whole let's stack people side by side on desks, rather than give them some nicer spaces with lots of room for deep thought. When I was working for HARC, we had a nice former industrial space near UCLA. I totally could go for that, but when the only way to get something semi-nice and private is to work at home, well, that is going to bias people.
Anyways, it isn't a mystery why people want to work at home these days, and they don't really need to be in the office anyways considering how hard it is to get conference rooms to VC all the time with your partners across the country or world.
