For remote, the way Linux kernel or BSDs are being developed, one needs nothing but git, emacs and browser (well, in case of Linux also a working mail) and no management at all. How could, say, Amazon, even hypothetically switch to remote?
More seriously, there is no market for code - otherwise people would just pay per commit (passed all the tests) nice and easy. The problem is people with money doesn't need a mere good code, they need their positions, their bonuses, their status. They will pay you for filling a slot in the social hierarchy which supports them, not for your good code.
This is why, perhaps, remote works fine for "nonprofits", like FreeBSD, but for corporations it is still a heresy.
Again, there, it seems, is no demand for mere good quality code.
This, by the way, is connected with hiring. Almost no one hire for abilities, everyone is hiring for good school diplomas. (Which diploma Mike Pall has? Igor Sysoev was a college dropout).
If I am wrong, and there is a market for code - solved problem, pushed a commit, all tests passed, money transferred - please tell me, I would participate gladly.
