So far, Tesla has been a blockchain, energy, robotics, and now a compute company.
Musk made some bad bets, but also some good ones (Falcon rockets, Starlink) and some at least promising ones (Starship, Neuralink). And Twitter bought him enormous political influence - I wouldn't consider this a failure either, from the realistically-cynical point of view. That cannot be measured by revenue alone.
Musk has been coasting on his successes from 10+ years ago. He has nothing good to offer anyone in 2026.
Would any VC(one without a conflict of interest) invest now, for the long term, based on those visions?
