Ask HN: How far do you think we can enhance GPT-4?

There have been a number of GPT-4 variants and expansions that show improved results over the base model. Some relevant ones I can think of allow GPT to:

- Reflect on its own behavior (Reflexion)

- Function autonomously (Auto-GPT)

- Use external tools (HuggingGPT)

- Have long-term memory (Retrieval)

I'm no expert on AI or the human brain, but it seems to me that with this we would have all main elements of intelligence. If we could think of an architecture that combined all these extensions, added fine tuning, and maybe integrated it with some form of generative AI (to generate new ideas), do you think such a system could approach AGI?
