Insight
Horowitz: AI agents will destroy traditional software moats like UI lock-in
“So it's very easy to replicate the code. It's very easy to move the data, and then it's not even going to be a human talking to your software. It's going to be an AI, and, you know, AIs are really flexible on how they use user interfaces, so That mode is gone.”
