[Number 3]

OP, a good discussion topic, but not sure where you come up with the loss of MILLIONS of jobs. The people that make engines today will make electric motors and batteries tomorrow.

The shift will not be when we run out of oil as suggested, but simply when it is cheaper to drive and own an EV compared to an ICE. That is the tipping point. And with so many people trying to make that work at all the big OEMs and tiny start ups, it will be sooner rather than later.

As for autonomous vehicles that too is coming sooner rather than later. There is a company that has hundreds of young engineers working ridiculous hours (they are fed all meals) simply working on coding and programming. They update their test fleet every morning with coding done the previous day from data downloaded at the end of the previous day. They are working at a rate that is beyond anything I've seen for one purpose.....to be first.

For autonomy, the companies don't want to make the hardware. Ultimately that's a losing game. It's the software that runs it.

We will see huge differences mid next century.

Just to further the discussion on autonomy, look up The Trolley Problem. The software in your autonomous car will make that decision.
