In practice, the technology will improve. I'm still waiting to see where the ceiling is to know how many people will keep their jobs. I see similar articles about codex, and v0 won't take my job, but v3 might. Or v3 might be identical to v0. It's too early to know.
What I have found all these tools to do is to make me use whatever they generate far more. There was a pretty high bar for custom illustrations before DALL-E. With DALL-E, my last presentation had a half-dozen custom images. It was awesome. I'd never hire an illustrator to do that, but I definitely did "hire" DALL-E.
codex and gpt-3 are starting to change how I work.
If I use illustrations 10-fold more, which I seem to be doing, will illustrators get more work? Less? I don't know.
It is a brave new world, though.
