He hasn't given up on self-driving after it turned out to be much harder than he thought. He's still pouring money and time into it.

And he hasn't given up on Starlink, even though it is not nearly as profitable as he hoped originally. He's just launching more satellites.

And he hasn't given up on Starship even though it is years late. He's doubling down on its development.

But I conceded that he might not see Twitter as critical for his ultimate goals. Maybe he'll just sell it to a bigger fool in a few years?
