Secret sauce, no clue. Some folks are working on AGI precisely looking for that secret sauce. ChatGPT is just a tool, a very clever one. Just as a chainsaw cannot drill holes, ChatGPT cannot do many, many other intellectual tasks. We have other very clever AI tools. All can fool humans as well. But I imagine the first phones or TVs also fooled humans. Tools, just tools so far. I think even if we ever build an artificial brain and wire it correctly, it will still be just a tool. I think AGI is not a hardware problem but a software one. Given the necessary hardware, can we program AGI?
