I'm mostly trying to extrapolate from current code and text generation abilities, so I know any prediction has a high chance of striking out.
Legal professionals that work on boilerplate could see simple contract generation being taken away from them for instance, and even run-of-the-mill developers could see themselves competing against much cheaper app/website generators.
Even if you can beat the AI, you might be forced to make your rates more competitive since the new baseline solution anyone can get for $10 would be a lot better than before.
