  1. Our readingAI writes code well only where a million repositories have already written it; getting it to do something genuinely new remains notoriously hard.

    Their wordsAI is really great at spewing out code that does something that a million GitHub repositories already do because it's learned the underlying pattern. It's notoriously hard to get to do something new that hasn't been done before, especially when it's a complex task.

  3. Our readingA compelling simulation of a human being could arrive within five years, and the technology is heading there whether or not it is a good idea.

    Their wordsWhat we're seeing with generative text AI is not only at a level that you could say that it's actually doing a pretty good job of simulating a human, at least humans at the text level, not at the emotional level yet, but at least at the level of words spoken and find more and more ways of training on more and more scenarios that you might have a very, very compelling human simulation going on in the next five years even. I'm not saying it's a good idea, but I think the arc of the technology is inextricably heading in that way, and it's heading at a shocking rate.
