I've also been using Linux for about 20 years and I would happily switch to Fuchsia if it had good hardware support and worked well on servers. POSIX is just a bad API spec, I'm personally sick of programming for it and dealing with it. It seems to me that new things like eBPF are just papering over the existing problems, which everyone is afraid to address out of fear of breaking legacy software.

But I actually don't think this will happen with Fuchsia and I expect to just deal with the problems of Linux for another 20 years. Oh well.
