If they're right:

* Use AI to eliminate all white collar jobs.

* Combine AI with robotics to eliminate all blue collar jobs.

* Combine AI with military hardware to kill any rabble who may become threats to the ruling class.

The most optimistic outcome is that it doesn't happen in our lifetimes. Aside from that, the best you can hope for is that the ruling class enslaves the rest but treats them well enough that most don't realize they are slaves (e.g., the Eloi from the Time Machine).

I'm cautiously optimistic about the former, but I expect the resources required by the latter will far exceed what the greed inherent to the ruling class will allow without first purging a significant fraction of the population. All we can hope for is they stop the purge before it takes everyone not in the ruling class, but given how many ultra-wealthy individuals already see the rest of us, I wouldn't bet on that.
