Well, recursively trying to perfect lower layers is what I am advocating for us to not do.

As a guy who prefers to stop and think before coding, to me a lot of the older UNIX / GNU primitives seem broken (like the env vars process inheriting discussion that was here a while ago) and should be completely rethought. I also think people overreact and believe "everything will break". And we have libraries and runtimes that only implement small parts of libc and the deployed apps that use them are running mostly fine for years.

My broader point was: shall we not start breaking away from all this legacy? Must we always rely on corporations to lead the charge?

But yes, I do of course agree with the only 24h a day thing. And likely nobody would want to pay for such a trail-blazing work anyway. Sad world.
