Hmmm I learned that Fuchsia is related to Haiku.
No, I know one person who uses it as their main machine though. Do you use it OP? How's the software support? What about the license? Is it libre? Is it similar to gnu/linux? I dislike most operating systems nowadays, I can tolerate gnu/linux because it's not spying on me which I believe is a sad excuse to use some piece of software and I think that's telling a lot about modern OS development. I wouldn't mind switching to something completely different.
