You probably know this, but just want to say, founder to founder: don't listen to this argument at all.
People are so fond of saying "just wait and the new model will do this." And very smart people I know say it (especially when they work for OpenAI or Anthropic!).
It might be partly true (of course it's situational). But it's a glib and irrelevant thing to say. Model capabilities do not advance like some continuous exponential across all domains and skills. Not even close.
Product design is exploring the solution to human problems in a way that you can bundle and sell. Novel solutions to human problems tend to come from humans, applying effort over time (with the help of models of course) to understand the problem and separate out what's essential and what's irrelevant to the solution.
