Why you might want a remote dev environment

Fearmongering aside — and Cthulhu knows there’s been a bunch, since this unfortunate tweet — there’s a bunch of reasons to want a remote dev environment.

As the popular saying goes, there are only two hard problems in computer science: caching, off-by-one errors, and getting a Rust job that isn’t cryptocurrency-related.
