Like, autonomous vehicles should rely solely on visible light cameras? That went famously well indeed. What a smart man.
Or that we should dig tunnels to drive cars in? Yes, we now see he was right all along. Or that the US government could save trillions of dollars by using tech instead of people for running things? One of the most successful ideas of Trump 2.0. And the list goes on. Tesla made a decent electric car, on par with other electric cars, just falling behind on self driving (fsd is not self driving, according to Tesla). Space X built some good rockets that can do what NASA can; just killed NASA in the process by siphoning away the federal budget. Starlink is good satellite internet. Exploiting an orbital space that nobody was brazen enough to just claim and take without any public approval. Got to give him the credit. He is good at taking away things and claiming for himself that nobody else dreamed of taking.
