He would have understood the potential of LLMs straight away. If he would have delivered a successful product no one knows but 100% would have understood how LLMs could become another interface to computers.

I suspect Jobs would have held off for a few years just to see where the road is going before making a move. In that sense, Apples current lack of real dedicated to move into the LLM space has become a happy accident. They have avoided the hype cycle and the potential blow back once the more exuberant part of the AI craze fade away.

They have pulled an accidental Jobs move.

He for sure would loathe their current state though. They are a perfectionist's nightmare and detrimental to many brands. He wouldn't even allow Apple^Red for his friend's charity- there's no way he would let AI slop come from Apple products.
