We're seeing a cambrian explosion of applications in AI
Auto-GPT May Be The Strong AI Tool That Surpasses ChatGPT
Seriously, software engineering as we have known it is dead in the water.
This AI is better than at least 95% of coders. And to the extent it is not, it delivers 1000x productivity improvements to complement them.
We have now officially entered the Age of AI.

Simple LLM technique that helps a lot (but you might not be using): add a constraint checker to ensure valid generation. On violation, inject what was generated and the rule violation, and regenerate.
