Just a few thoughts about the hubris of Elon Musk...

I really don't think that paying 40 Billion dollars for Twitter, which has never shown a profit, it all that smart of an investment. Musk does have his blind spots. Such as his refusal to incorporate lydar as part of the self driving system in Tesla cars. I think in retrospect his refusal to use lydar, will be compared to Edison refusing to consider AC as a standard for electricity. Virtually every other self driving system uses both cameras and lydar systems, which makes the self driving system(s) much safer. To have to go back after the fact and redesign the Tesla self driving system after the fact may cause the company to lose enough money for the company to go under.
