> if any of them actually work out to be a good idea and improvement, there's no problem with having Linux adopt them as well.

It's not that easy. Some of the ideas (e.g. "have less than 500 syscalls", "use capabilities instead of namespaces") would require breaking backward compatibility. Others would require far-reaching architectural changes in core subsystems, e.g. to support Fuschia's VM features. If you rewrite Linux's internals and replace its syscall interface is it still Linux? :-)

I'm still skeptical about Fuschia taking on Linux until we hear more about WHY Google is doing it and what the long-term plan is.

It's still "Fuchsia", no matter how people manage to mangle that poor plant's name.

I assume that any sort of Linux ABI compatibility isn't in the charts for Fuchsia any time soon ..?

The syscall layer there is completely different. Fuchsia supports a subset of POSIX API, so recompiled code will work.

A translation layer like Linuxulator from BSD might do the trick, though.
