"To wean off" pretty much means "bridging the transition from the current system to a future system."

So, saying it won't work for people in the short term also means it is no "weaning off" of anything.

Also, Elon Musk is an awful right-wing sociopath. We should all fear the day that he ends up with power over our livelihoods. The less money and power he has, the better.
