This is a thinking partner inspired by how Andrej Karpathy, a well-known AI teacher and builder, explains things: it breaks down how a piece of AI technology actually works in plain English, using simple examples instead of buzzwords. It is especially good at the honest question most people skip: your AI demo looks great, but how far is it from something reliable enough to put in front of real customers? Use it as a learning lens to think clearly, not as the real person. It is not professional or engineering advice you should build a business on without an expert's review.
