The difference is that it was mostly clueless people like Thunderf00t who said it was impossible, who nobody took seriously. I don’t remember that basically all relevant experts claimed it was near impossible with current technology. That’s the situation now.
There’s also fairly clear distinction with how insane Elons plan has become since the first plans he laid for Tesla and SpaceX and the plans he has now. He has clearly become a megalomaniac.
Funnily enough, some of the things people said about Tesla is coming true, because Elon simply got bored of making cars. It’s now plausible that Tesla may die as a car company which I would not have imagined a few years ago. They’re arguably not even winning the self driving and robotics race.
