My general prediction is that we'll see an immense amount of wealth creation and this will naturally trickle everywhere. This is both a continuation and speeding up of the trend we're seeing right now. I think the unusual outcome would be for us to stray from this path.

So perhaps I can finally rest and solely focus on the stuff that I like. For this to be a problem, we need to imagine a dystopian scenario where our systems (and those who run 'em?) are effectively all-powerful and also cartoonishly selfish for no good reason at all.

You can do that now anyway, but you aren't.
I repeat my question - how do you imagine the economy will function if humans have nothing of value other than janitorial work to offer?
