...to create stuff using AI, its commercial value will drop to zero
I don't think so. And also: I'm old enough to remember at least two times before were AI was "on the brink of revolutionizing everything". I agree that this time we're closer than before, but:
One, AI is still no guarantee to get what you want.
Two, sooner or later people will realize that if you can describe what you want in enough detail for an AI to do it, you could get a human to do it as well.
Three, the immense cost of AI is currently shouldered by a couple companies with deep pockets (or investors with such). Once the hype has gone down and people ask for ROI, prices will raise.
Four, in everything that I've used AI for so far, I would rate its competence level at intern - has some basic knowledge, mostly knows what it's doing, you definitely want to check the output for mistakes.
Five, there are still plenty of creative things that AI doesn't do, or only does in very specific ways. When you've done enough text or image generation, you start to see the patterns. The repetitive outputs. The difficulty of getting the AI to give you a DIFFERENT output once it's gone down one path.
Six, as AI is training more and more on AI output, quality is already dropping in some areas. For other areas, it's a real challenge to find good training data. Many of the coding assistants are trained on StackOverflow and similar sites, and they are good for producing example code, and terrible at producing performant and secure code.
In summary: There are still enough challenges in AI and it's way too early to predict the end of the human race, again.
