Since we are talking about AI, I'll bring up one thing that hasn't changed, or hasn't been solved at least by AI. Understanding. We are producing so much more than ever, yet we are not understanding the world better.
You can experiment it yourself, just because you have the world's knowledge at your fingertips doesn't make you an expert in every field. I asked an LLM to teach me everything I need to know about batteries so I can get into the business. All the information is there, a well crafted curriculum. The amount I didn't know that I didn't know before starting is depressing.
Extend this to the idea that now everyone knows everything about everything and you'll quickly realize that we still don't understand much about anything despite this powerful tool on our hand.
Understanding things still matters.
