Unfortunately a lot more than 25% of the workforce is at risk for automation. Retail, manufacturing, housekeeping, accounting, machining, farming, construction (they are rapidly working on 3D printed buildings including skyscrapers made of printed nanotubules).
What this really means is that we absolutely must bring new economic models into play, such as UBI. Without such, consumers will have no money. Without consumer spending, capitalism will collapse.
So you can find great irony in the fact that the only thing which will save capitalism will be a Socialist economic model.
Once that is in place, then there will likely be an even greater demand for human artistry.
