Aye.

It me. That said, I didn't buy TSLA because I was expecting to cash out a few years later when he started acting like a threat to democracy and his own judicial system; when I bought it I thought they had a good business model and I thought they were undervalued.

Now they're overvalued, have lots of visible competitors eating their lunch.

Worse, even if they succeed, given Musk has yet to pay out dividends on that stock and also enough control over the board to give him as many shares as he wants, I think even success would render the stock monopoly money.
