Let's build AI with constant run time.
Let's build AI without memory.
Let's build AI that doesn't want to do anything.
Let's build AI like a hammer rather than a DoAnythingNow with hammer skills.
If you insist that you need DoAnythingNow then set up some extremely streamlined data generation & training processes, so it can do anything when you ask it, rather than learning everything in advance just in case.
Most of the stuff I ask GPT etc for doesn't really need natural language. Natural language is not even a very good interface for eg most code stuff. I would much rather click a "fix bug" button.
The first general AIs learned all of everything in advance, but I don't see any good reason to keep doing that. I see lots of good reasons to eg learn on demand and then forget.
Let's build a tool that feels like a tool and works like a tool. A magic shapeshifting tool is ok. But I don't want a slave.
I don't need my coding assistant to grok the feelings and motivations of every Shakespeare character in depth. A customer service bot will need some basic people skills but maybe skip reading Machiavelli.
Let's build AI that can only do what we need it to do.
F, E, E, D, C, B, A, A, A, A, A, A, A, A
The As start at "Single-celled organisms, bacteria".
There's rather a jump in your list from sleeping humans to insects. How about, say, elephants? I'd give them a D.
ETA: For the second list: E or D for all the animals (I'm not sure where I'd switch, if at all), A for the rest. I'd go down to C for, say, earthworms, but what I would really mean is more of a D for there being anything like consciousness there, but it would only be a smidgeon.
