Can't speak to the OP, but lots of technical work (and frankly many trades are also technical) doesn't lend itself to text based documentation and teaching. Software, translation, non/fiction writing (like marketing and sales) all do. I think LLMs will take a significant part of those businesses, because I don't believe there is a Devon's Paradox for code -Tractors- Agents.

At the same time medicine, hardware design, good industrial, and specific domain knowledge (problems you solve in assembly or control loops) that are fundamentally proprietary and aren't well documented will continue to have value even when LLMs make solving the problems around them easier. Those might have increased leverage, at least for this round of LLMs. Now, maybe they succeed in World Models, but that is not today.

Really, I don't know what "kids these days" are going to do. I couldn't have predicted the influencer boom 15 years ago, but I also think there are geopolitical risks that are probably bigger than that shift, and "synergized" with the push to AI Everything, it doesn't look like a good time to be a learning/working human.
