Many of the comments here resemble Reddit, disappointingly. I read HN due to market insights, analysis, interesting perspectives. I am sorry for digression.
Are there any other explanations that can be steelmanned, just for the sake of an even-handed discussion? "We're going to build humanoid robots" just doesn't seem like enough. Neither does "We're going to build robotaxis", considering that other companies like Waymo are already well ahead of Tesla in that sector.
So the optimistic valuation is based on: Global ride share killer + Large car manufacturer + power infrastructure + Robotics.
Somehow the valuation is as though TSLA will succeeded early enough to entrench itself; if robotaxi wide rollout happens in the next six months, i would be happy to say TSLA is worth more than its current valuation. If it cant then at best 30% of current valuation.
No worries, in 6 months Elon will promise something else and we'll be asking the same question again
