This is automation on a scale that we have not seen before where machines are actually capable of decision making and precision work. This is combined with a massive concentration of wealth at the top. Also there are a whole lot more people now. Potential long term could be colonization of the moon / mars. Plenty of unskilled labor required and opens a new frontier.
It's not at all obvious to me that colonization of another planet, if we're ever in a position to actually undertake it, will involve "plenty of unskilled labor".
Agreed. Pretty much the opposite, actually - shipping, housing, feeding, etc. a bunch of humans is obscenely expensive in the context of space exploration. You're far better off sending a bunch of robots with a couple mechanics to keep them running. Additionally, I'm pretty sure that by the time we're in any kind of position to do actual colonization efforts, automation effects will have long since taken their toll.
