Let me be clear: Musk is human. He has positive and negative qualities. His Thailand pedo comments were, to put it bluntly, fucking retarded. His autopilot timeline was wildly optimistic. His behavior on Twitter is infantile.
And yet this is not carte blanche to twist his words into something unrecognizable. You can't just criticize someone for not being nuanced, then criticize their disclaimer that happens seconds later. That's intellectually dishonest. At that point I stopped listening because it is clear (to me) that the youtuber has an agenda to push.
As to your comments, I'm not sure what you're trying to say. Is it incorrect to believe that brain implants may lead to solutions to these problems?
