What amuses me about this hype is that before I see borderline practical use cases, these AI zealots (or just trolls?) already jump ahead and claim that they have achieved unbelievable crazy things.

When ChatGPT was out, it's just a chatbot that understands human language really well. It was amazing, but it also failed a lot -- remember how early models hallucinated terribly? It took weeks for people to discover interesting usages (tool calling/agent) and months and years for the models and new workflows to be polished and become more useful.
