I agree for the most part - as
@StealthP3D says, a low SP do benefit the workforce - but I don't buy the fact that Elon "discovered" of the energy usage of Bitcoin after he bought it.
This article cited by
@JRP3 tries to put the puzzle together:
There has been a lot of action around Tesla, Elon Musk and crypto. Read why the action so far is a mystery which will reveal yet another hype angle for Tesla.

The gist of it is that Musk has a long story with crypto - both Bitcoin and Doge.
He has criticized Bitcoin for years, even about energy consumption (can't find the tweets because Twitter search is awful). Then he changed his mind. Then he changed it again in a week or so.
His whole reasoning is too inconsistent to take it at face value. There must be some information/background we don't know about.
