A hundred years ago, we have mutiple car makers striving for market share. GM combined a number of them under one umbrella, and we might see that again. I don't see any of them having any special particularly advanced technology over any others. They have some features that are nice, or not. The space will shake out over time obviously, I don't know who is left standing, who gets acquired, and who goes under.
Short term I have some nice paper profits (in my IRA), which really are not much. It about balances my losses with Nikola, so I could sell out now and be flat.
I allocate a portion of my investments to risky stuff, around 3-4%. Some of it catches fire, some flames out.
I'm curious about the GM "Ultium" battery pack. I think it has some potential, but I don't have GM stock now.
