As I said, I can write programs in assembly language. I have actually done so, small trivial ones. I'm not a businessman, I'm a programmer. But I use compilers basically all the time because it would be ridiculous not to.
If an AI is able to break something in a way that no human can fix then I suppose that's a sign that AI has exceeded human capabilities. Do you think it's there yet?
Having transcripts of every adventure is such a huge game-changer for me. I've been putting them into NotebookLM and I can ask it any detail about past adventures, "when the party met with the prince did they mention anything about the vault to him?" Or about the worldbuilding, "who was the goddess of tears and rain?" And so forth. Drop a PDF of the rules in there too and it can look up stuff that may not be so easy to just keyword search, and in a pinch it can even do stuff like whip up a new set of monster stats (though I've found it's not very good at balancing them so you'll need to give it a once-over).
I've been experimenting with tools like llm_wiki, which can automatically build an obsidian-compatible wiki out of raw source documents (such as those transcripts). It's not quite "there" yet IMO but it looks like a promising approach.
