No, your vaporware office scenario still isn't going to get me to come into the office. :-)

And I find it very hard to believe. When I started working in the 1980s, everybody got a cubicle, we didn't even like cubicles!, but you had walls and it was quieter and people treated it like your personal space.

In my last job, I could've stood up and put my hand on seven different people's shoulders without moving my feet.

So your quiet shielded office doesn't sound like anything an actual company does.

> you’ll need to surrender quite a bit of that to interruptions when remote -

No, you get a lot fewer interruptions when working remotely than in an office. Deliveries do not take an hour a day, particularly when there are two adults who can split the task.

Pet interruptions take basically zero time per day because they aren't actually an interruption: I don't have to stop thinking about my problem for one second, but if I have to answer a single question about some other technical thing, I blow away my whole thought process and have to build it up again.
