TaaS needs to be grown from zero and might have some roadblocks. I'm optimistic about FSD and if Tesla wins
that race combined with their newfound chip manufacturing prowess then I think most of these valuation discussions are immaterial, we'll be arguing about whether a single TSLA share will be worth $100k or $150k.
I'm pretty sure they'll do it. Reading between the lines I got the impression that they already have their cobalt-free li-ion chemistry, but are iterating it to maximize thermal stability vs. performance, which needs 1-2 years to complete.
Also, after the tear-downs earlier this year everyone else started copying Tesla's and Panasonic's NCA chemistry, which has put significant pressure on cobalt prices this year:
That's a price reduction from ~$42 to ~$27, a nice %35% reduction this year alone. It appears the market doesn't think that cobalt is going to be a problem.
