> It used to be that if you got stuck on a concept, you're basically screwed.

Given that humanity has been able to go from living in caves to sending spaceships to the moon without LLMs, let me express some doubt about that.

Even without going further, software engineering isn't new and people have been stuck on concepts and have managed to get unstuck without LLMs for decades.

What you gain in instant knowledge with LLMs, you lose in learning how to get unstuck, how to persevere, how to innovate, etc.
