Do Googlers mind working in the office much? They get plenty of free meals/snacks/beverages, great equipment, and great salary allowing them to live close to the office and pay for childcare if needed. I can't see the rest of the industry moving in the direction of returning to the office, because they don't have these things.
If you want my opinion, open space sucks and I can buy my own snacks. After one day at the office, I feel my head is about to explode. Constant noise, bright artificial lights... The only good thing is that I can have informal meetings with my colleagues, talk around the white board and so on... this is very valuable.
If I was getting paid the snack amount in cash then I'd probably be ok but as is free breakfast+lunch+snacks saves me on the order of $500/mo. And as someone who is pretty mediocre at cooking the quality of food is better as well.
