An example of a purchase I made recently is this $15 bimetal heat break: https://www.amazon.com/dp/B0C5VSK1V8 it's basically a part that allows you to 3D print at higher temperatures. To figure out that this was the right product I wanted, it took a couple minutes of research, looking at diagrams, searching recent reddit and youtube posts, etc.

If I would have asked an LLM, it would have told me to buy an all-metal hotend that costs $70 or more, based on outdated advice.

I don't trust LLMs for out of the box thinking because they have no idea what is going on in the real world. They are fine for discussing general aspects of well-documented and often-discussed things like taxes, cooking, or gardening.
