Once Tesla went away from designing a new cheaper platform in order to go all in on AI (this was reported, everybody was against Musk on this), I lost complete confidence and sold all my stock. My investment concept was never build on AI, but advanced technology (AI driving assists is useful value add, but not a silver bullet), vertical integration and mass manufacture. Once Musk started making the argument that Self Driving was going to reduce amount of cars sold by 80% I realize that he has completely lost touch with reality. His believe in AI despite tons of evidence is his biggest weakness. Stripping a Model Y isn't a long term plan. Its just a short term slight increase of car sales at best.
