And what
@splishsplash says I usually follow blindly. But notice that I said "usually", which means NOT always
In this particular case, if the guy is right then you still have few years ahead of you to make money, so go for it! And stop being "workaholic", life should be about balance and happiness, not about working like a dumb mule (just a manner of speaking, please don't take it literally as I couldn't find a better comparison)
And if he's not right then google will come back to their senses and start showing relevant results again in a few years after they notice how their shitty AI doesn't bring them any money (especially if the governments worldwide will step in and restrict the use of AI like they should be doing anyway) or that it destroys a lot of people's lives. And if this happens (governments stepping in), then google will have to go back to traditional SEO in which case your sites will continue ranking.
Personally, I don't think this will ever happen, but my opinion is not always the same as yours, so I wanted to mention it so that you can decide without being under my influence
