Another smart guy that is almost as rich is short tesla ie Bill Gates I don't know or care about who is right and who is wrong just saying your investment should not be purely based on Musk name. Personally I think Tesla might win the car race but as prices for electricity, batteries and pc chips keep going down. I am not so sure about self driving cars being worth that much as it will be race to the bottom in terms of price and cost.

Cheaper electricity is coming that is the bigger change than most people realise not electric cars. So far majority of electricity has been produced using fossil fuels a finite resource where as solar is practically an infinite resource price for harvesting it as well as storing it keeps dropping.
