I'm with you on two key points:
- Prototyping is amazing, and provides real and dramatic benefits.
- Generative AI is an amazing protyping tool.
But the value proposition falls to pieces if we compare the costs and impacts of LLM prototypes and paper prototypes.
Before LLMs were invented, there waa strong data showing that paper prototypes are insanely compelling, even when compared with easy cheap rapid prototyping software.
LLM prototypes just aren't a pragmatic option. (By the data, so far.)
