Yes, global warming is a hoax and Musk may even know this. But, as a businessman, he is providing a quality product to fulfill a desire for that product. That's the definition of a business. Musk didn't invent the hoax. But he is taking advantage of it. I can't fault him for this.
My conscience would never have allowed me to do this, which is why, I suppose, I retired poor, but smugly satisfied that I didn't make my living by cheating society.
I have no love for that company (though its done remarkably well).
However it allowed him to leverage to buy twitter which I’m grateful and I think we all are for that.
The inventor of the pet rock, Dahl, moved on after the hype to other adventures. SpaceX and Twitter are so deferent from Tesla and there is good chance neither will ever make what T-Bills could have.
Honestly the battery component of Tesla is needed for the US power grid, the overbuilding for Peak demands at the subdivision (100+) homes really is insane. If you can level 3-30 amps at 1200V volts to 6-12 amps the cost of buried and arial installs really goes away. Make that on something that gets dropped off like a shipping container and stuck in a corner someplace. Stanadarize the connectors for quick replacement, then 100 homes do not all “need” their own solution.
