Well we have cool projects like CollapseOS the problem is that there is so much undocumented silicon out there that cant be used without massive efforts. I know several "gold scrappers" and its such a shame that they trash great classic chips just go get back a bit of metal. So much effort went into making those chips and its just a shame that many can't be reused. While lack of cheap electricity prevents open design from being reused, there is an even bigger world of undocumented chips that are trashed as well.
