I do not consider Tesla predictions for future products as lies, but as rolling out their plans and objectives.
Many of these predictions are for products that do not exist yet, but expectations of an optimistic leader.
The case could be made that if Elon was not optimistic in nature, all these inventions would never come off the drawing board.
There would be no Tesla, SpaceX, boring company, PayPal, XAi, Starlink, NeuralLink, FSD, Hyperloop, Optimus, etc.
The projections often come about...eventually, but rarely perform has hoped, right out of the blocks.
Inventing the future is hard, and fraught with perils...Show me another man that has done more...Better.
