I'm interested in it from a purely technological point of view. Linux is almost 30 years old, and it's architecture is almost 50 years old. Xnu, which is the kernel of iOS is a bit more modern, but Apple has gradually moved it back towards a monolithic BSDish, posix-compliant kernel over the years. We've actually learned a few things about operating systems since 1970, and today's hardware vastly different from the time-sharing systems of that day. It would be really useful to just implement an OS based on more modern ideas and see where it goes. I have no idea what Google is planning for Fuscia, but I hope that's part of it.
