As mentioned, much of our discussion is rote parroting. I can usually go into any hackernews thread and roughly know what the top discussions are going to be. It's not surprising that an AI trained on a large portion of the internet would thus look human like.

If you really poke at GPT, you begin to realize it's fairly shallow. Human intelligence is like a deep well or pond, where as GPT is a vast but shallow ocean.

Making that ocean deeper is not a trivial problem that we can just throw more compute or data at. We've pretty much tapped out that depth with GPT4 and are going to need better designs.

This could only take half a decade or it could be half a century. Plenty of enterprises stagnate for decades.
