Only if you work with all people who highly value remote work. My office always has people there. And we have the option to work fully remote. Some people have never been to the office.
Finding the right company culture for you is often overlooked in favor of things like the right tech stack.
Yeah, our office now seems to always have at least 30 people at it, maybe as many as 75. Hard to tell for sure, I've never been, just judging by pictures people have taken at company meetings and the cacophony of chatter and office noise I hear when someone on my team hops on a meeting when they went into the office (only one person on my team does, and even they don't seem to go in more than 1-2 times a week).
But there's still plenty of people WFH, and plenty of people who couldn't come into the office if it was suddenly mandated (which it hasn't been yet, just encouraged), because they live several states away.
I'm almost certainly giving up a better bonus and performance review by not going into the office regularly and playing office politics, but it's a sacrifice I'm willing to make. I shouldn't have to make that sacrifice, but I never really played the office politics game even when I did go into the office every day, so not a big change there.
But 30+ people should be enough to get that "in-office watercooler" experience for those who like to work in the office.
