A union doesn't give you unilateral power; it just gives you a better seat at the bargaining table. Capital pools its resources to negotiate better as a single bloc; why shouldn't labor as well?
For your unique approach to the problems at hand. Yes, 90% of the code written is CRUD, but when it's not, how it's solved matters.
This is why we have grown with id Software games. They solved the problems, created new paths and methods for limited hardware for their time.
This is why we praised DivX and XviD back in the day. They solved problems again which are caused by the limits of the computers.
The way one solves problems matter, makes one valuable. This is why we do research and create new ways to do things.
In short, your creativity is being sold/sprayed to masses.
Until you actually remove the need for a human, you have to pay full price for human labor. Which if you used AI is never really going to happen. Someone has to evaluate what AI creates to make sure it does what was asked. This trend of not prosecuting crimes conducted by AI cannot last forever. The CEO would be the only one arrestable as the CEO is the only person with decision power in the company.
