TempleOS is way overhyped. It's a curiosity more than a useful OS or programming tool. Without applications that are useful and help people do things important to their work or other needs, an OS is useless. For all the years it was developed over, it stayed very primitive and lacked any significant usefulness outside of experimentation in a very limited environment. There have been so many other independent OSes developed over the years and all of them stayed at the enthusiast level for the most part. They all stayed there because no one did anything useful on top of them. Even GNU Linux still suffers from some of this because it lacks the unifying force of major apps helping to shape its future. I'm sure I'll get pushback on that statement, but it's the current year and we still don't have "Year of the Linux Desktop" as has been predicted for decades now.
