Remote work is about the only thing where I very much disagree with Musk. I get it for engineering physical things. But not for web software. In that area, remote works much better than in-office, at least for me.
I agree, but I think either full on-site or fully remote are both leagues better than partially remote. Partially remote is far worse than either - because now all the in-person tactics exclude the remote folks, and all the remote work tactics are an unnecessary burden to the in-office folks. An all-remote team of heads-down engineers is 99% as good as in-person, if not better, because now all the communication has been written down and recorded.
