Since the 1700s, we've been on a trajectory of more specialization to the point where you're a cog in a machine. AI is likely going to automate the specialist that has an average performance, but not those at the frontier. 

The people that get automated away will lose jobs but gain a new aim.

Rather than being forced to meet the hiring criteria, they can choose to be generalists and take their skills and combine it with new skills to create something novel. 

This is likely to solve the stagnation issue more so than AI automating creation itself.

Can specialists who are average at their job combine average performance at another skill to create something novel?

I think yes because when I look at coffee shops or social media influencers, by adding their own personality into it, it seems new.

Can you automate personalities? 

You could automate what they say on average, but not the relationship built upon trust.

AI won't automate those at the frontier because there isn't enough data to say what the correct output should be.
