This is, in my view, the biggest bummer about (what I see as) Musk's descent into madness in the last few years.
It's absolutely true that this stuff is capital intensive, slow, and risky, and thus hard to get investment for. But Musk had solved that problem using showmanship and a series of successful (whether through genius or luck, it doesn't matter!) risky bets to back it up. So I think it just really is the case that because of Tesla / SpaceX / Starlink, that he could easily get however much funding he wants in private or public markets to take a giant risky bet on something like geothermal energy.
But instead he got bored of doing useful things and lost himself in petty social media drama. Tragic.
He's got solar things already. How many companies do you want one guy to run? The more stuff he does, it doesn't mean the stuff he doesn't do he's somehow to blame for.
I didn't blame him, I said that he's a tragic waste of potential at the moment.
If he were throwing himself into any of his impressive companies, sure, I'd be singing a different tune. But that's not what he's doing, he's either ignoring or actively sabotaging those, so that he has more time to be a social media influencer. He can do what he wants, but it's not admirable.
He doesn't. His solar city acquisition was nothing but a bailout and solar city was gutted down to nothing. Tesla hardly does any solar installations except on their own factories.
The issue is with the lack of good quality startups than with financing really. Long-term is not a big issue, because funds can exit before the startup’s exit through secondaries. Also some of the funds in this field are ok with long term investments.
