Same here , I got addicted to a mud called realms of despair , smaug codebase, a derivative of Dikumud, I then ended up helping run a pretty popular server on the same codebase with some friends I met on the server. Bought a "learn c++ for dummies book" (even though it was programmed in c) and started modifying the server and the rest was history ;) I guess I was 14 at the time and I haven't stopped programming since. Gaming is definitely the gateway drug to programming and text based games are in some ways the most interesting form for learning due to not having to worry about graphics and immediately seeing results like you mention.
I've often thought about implementing "Claude plays" some open source mud. Seems like a much more pure form of experiment since it's all text.
You are right, it will certainly be used for evil, but the reason is not because AI is evil but because the people who use it are evil - will AI allow worse atrocities that we have seen in the past? Probably, new technology always enables new capability for good or for bad but we should strive to combat the evil in this world and not put our heads down and hope the world isn't changing. AI can also be used for good and let's focus on more of that.
