Two honorable mentions were Naming & Branding and UI Design. None of the LLM or generative models are great at this. Figma did attempt to create flow charts so it’s possible a different tool set may need to be field tested.
Much like my prior experiment with first principles reasoning, LLMs aren’t sophisticated enough to provide granular enough product and architectural design to be immediately actionable by a development team.
While I anticipate that eventually LLM tools could be useful enough to assist in product and engineering tasks, it still requires a human to design something that is ubiquitous, intuitive, scalable, and secure.
Bottom line: don’t spend a lot of time bouncing ideas off the major models, and certainly don’t believe the hype that these tools can magically produce GOOD software with a few AI prompts.
