Let's consider how this could play out:

If you need a lot of low quality code in a hurry, AI can definitely do that for you now. The path to making money by writing mediocre code for people who don't really care that much is going to look like managing a network of bots that constantly spit out a huge volume of code that kind of mostly works and if it sometimes doesn't then whatever. The people in it for the money can probably make a decent amount in the "high volume low quality" space.

Then there's the code that needs to actually work, or have some thought put into it. Consider the process of writing IETF RFCs. Can you get an LLM to spit out English text that conforms to their formatting? Absolutely you can. Is the RFC it emits going to be something you'll want to have the whole world trying to implement as a standard? Not likely. So the people doing that are going to be doing it something closer to the old way.
