“I wish them the best. I hope they do well. The car industry is a very difficult industry. There’s only two U.S. car companies that haven’t gone bankrupt, and that’s Ford and Tesla.

If it were not for two technology discontinuities, one being electrification and the other being autonomy, I think Tesla could not succeed without solving both.”
