The mission statement does need to be revised. And that's just fine. Tesla's mission is now even more ambitious than before. A new mission statement would reflect that.
I agree with
@ggies07 general sentiment, which I state as "batteries are the lifeblood of the transition".
I have to also say like
@Artful Dodger that they are necessary, but not sufficient to preserve society. We need either enough trained tradespeople / factory workers, or enough useful bots, or the sum of the two, to form the veritable army to install those batteries, connect those batteries, and install the solar+wind+? to fill those batteries, upgrade the grid benefiting from those batteries... This portion is a longer-term concern, but cannot be discounted. We are decent at shiny new tech; we are often poor at recognizing and implementing the need for squishy, hard to quantify, politically dicey things like large scale human job retraining. A nice measurable "300 Wh/kg" is much easier to get behind (if you are in the know anyway
)
The boring, not shiny, long slog of retraining phalanxes of humans part just doesn't sell. Yes, a job market will eventually sort that out, but in time? Without mass political upheaval, already long simmering due to factory automation taking jobs in general, more recently the renewable+EV transition creating resentment to this actual effort, not to mention growing climate change driven unwanted migrations in the Americas, Europe, as well as every other continent?
A phalanx of shiny bots sells better, if they can be made to work. Hope that happens forthwith. And fine, they will have batteries, but to me that's really not the point.
