While the cross-pollination of ideas from different teams and departments is lost, along with interesting and serendipitous discussions, I'm also in the boat of hoping I never have to go back to an office. Not having a commute, being able to spend more time with my kids, not eating less-healthy fast-food rather than home-cooked meals, being able to spend my (lunch) breaks working in my garden...

Offices don't have to have terrible meal options. Nice homes can be chosen close to work, thereby negating commute. And co-workers don't have to be inept to the point of constantly interrupting your work flow.
There will always be a section of the population happier and more productive working from principally home. (Though for how long we can command a wage premium remains to be seen.) But I suspect, if offices were a bit more desirable and city center housing a bit more affordable, that slice would narrow quickly.
