That's fine as far as it goes, but there is a middle ground ...

Feynman was right that "If you can't build it, you don't understand it", but of course not everyone needs or wants to fully understand how an LLM works. However, regarding an LLM as a magic black box seems a bit extreme if you are a technologist and hope to understand where the technology is heading.

I guess we are in an era of vibe-coded disposable "fast tech" (cf fast fashion), so maybe it only matters what can it do today, if playing with or applying towards this end it is all you care about, but this seems a rather blinkered view.

The problem is that not even the ones building them can understand it. Otherwise they wouldn't be breaking their "I promise AGI by the end of next year" promises for the Nth time.

That or they are flat out lying. My money's on the latter.
