I'd look to the past at similar 'revolutions' and what it did to existing players. For example 'computer' was the name of an occupation that existed for millennia. [1] Yet so complete was the obsolescence that I think most people (certainly including myself) never even realized these people existed, but it's quite obvious once you think about it.
Imagine all the work involved in, for instance, trigonometry and its basic applications in the past. And the later on with the advent of kinematics and so forth. These things involved a lot of computation and so there were literal human calculators whose job it was to work out all of the calculations.
But with the advent of electrical calculators, we literally no longer know that these jobs even existed. It's very easy to see the same in a future where, for instance, computer programs can be efficiently written from description alone. At that point the idea of a 'programmer' would seem like quite an odd concept.
I'd also look at what it did to the value of such work. Now computations, even quite complex, are mostly worth exactly $0. But we built extensive systems on top of those computations that became worth quite a lot indeed!
