No, now they're even more important because they can protect your code from corporations. Yes, AI can recreate something similar in terms of functionality, but your code will remain your code, and not turn into Oracle's code, as often happens with OSS licenses.

I can think of 10 different ways to monetize everything you got but everyone just ignores my business hat 🙄 since forever. i'll shut up now

You can either create a derivative or something very sloppy. We don't have a legal non-GPL Blender alternative, with the same level of functionality, and as good as it, do we? Blender uses the GPL so that it stays free and open source software. Copyright is owned by contributors and this reassures everyone that the program will stay free. Of course, you may point out the Blender Foundation is a non-profit, not a company and surely not a start-up. But, in most instances, software freedom is not the way to go when maximizing profit and hasn't been for decades. When software freedom, not money, is the goal, free software licenses make sense. And while I'm not a huge fan of copyleft, sometimes the GPL makes sense.
