The expansion of AI hiring positions as announced by Elon is fantastic news, in more ways than one.
The obvious: FSD is HARD, harder than thought, but only Tesla is solving it in a fully frontal systematic manner. It may come late w.r.t. Elon time, but will definitely be before anybody else. The new hiring spree indicates that Tesla lead is even larger than I thought (make the lead 3 to 8 plus years). One can not of course compare Tesla FSD to the geofenced crap, with those silly 10 000 -30 000 Euro Lidars sticking out on top - those can never, even if fully functioning according to the seeked for specs, become mass market. Geofenced cars are a show stopper for a personal car, lidar adds a prohibitively high price and prohibitively lowers range due to high air drag - even if lidar gets to be solid state, the geofencing part really is a completely wrong approach.
The not so obvious, but potentially DRAMATICALLY increasing Tesla valuation: ROBOTS! Even humanoid, Asimov like robots! Fully functioning robots to nurse the elderly, to serve in homes (cook, clean, etc), to work in factories, ... ,... The market for this is in trillions (ignoring the military implications).
The reason Tesla could be the first company (say in 5 - 10 years) to crack this market is because of its R&D regarding AI in FSD. The software and hardware solutions that enables a car to safely drive in any, non geofenced, space is a crucial, not yet solved, component that allows future robots to interact with any environment - interact safely with humans, handle rooms, not break things, etc.
If this Tesla software and hardware is combined with some existing robot solutions, the sky could be the limit. I would not be surprised if the Tesla Israel R&D facililties takes an important role in this.
At the end of the day, such smart robots would be a very important part of the Mars colonisation project, making this development even more likely
So yes, I think ARK is too conservative in its bull case. Mine is 50 000 dollars within 20 years
Not an advice ;-)
