If someone wants to make an AI trading bot, give it money and let it trade, I think it's possible. It is also possible, of course, to use AI as some kind of investment advisor and ask it about what to purchase, to see whether it would recommend Bitcoin. But unless you mean one of these two options, the others are right that we're not currently at the stage of sentient AI making its own decisions. So there's no threat, and it doesn't matter whether AI views BTC as better than fiat or not, and for which purposes.
