Zuck is not a visionary. He did a half-assed and totally unscrupulous implementation of something was already happening with or without him. If MySpace hadn't been as dumb, mercenary, and backwards as it was, Facebook would be out in the weeds somewhere or else bought up by another player. As it is, it looks like the social networking market settled for second worst.
Musk may not be a good guy, or technically capable of doing anything at all without hiring smarter people to do it for him, but he does have vision. I'll grant him that.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.
