I think that's a key question, but I've never been a fan of the notion that robots (or efficient frameworks) are going to put us all out of jobs. If you look at what we've actually seen in the last 20 years, efficient frameworks enable entrepreneurship and wealth creation on a scale that wasn't possible in the past. Sure, there are fewer people employed doing nitty gritty stuff, but the size of the economic pie is far bigger than it once was, largely because of labor-saving technology and frameworks. If you want to argue that better frameworks will drive down wages, the argument to make is that better frameworks will reduce development time without facilitating wealth-creation.
EDIT: maybe this will happen, I can't predict the future. Rereading your post, I guess this is more or less what you were saying. But then the question is, what's going to change to reduce growth?
The argument is that the pie is already unevenly distributed. In the future, it will be even more unevenly distributed, and the skewing of the distribution will outpace the growth of the pie.
More importantly, the people at the top need the people lower on the ladder to pay their salary, either through companies that advertise or by paying directly. There may be an implosion at the top if they automate too many jobs away before magic market forces create replacements.
