The fundamental thing that is lacking in AGI research, and always has been, is knowledge of how brains work.
This is my sense as well. I also think there is a substantial limit on what we’re likely to learn about the brain given that we can’t study brain functionality with large scope, neuron-level definition, in real time given obvious ethical constraints. Does anyone know of any technologies on the horizon that could change this in the next ten years?
“One of [the Middle Ages’] characteristics was that ‘reasoning by analogy’ was rampant; another characteristic was almost total intellectual stagnation, and we now see why the two go together.
There’s no reason to spread such myths about medieval history.
The main characteristics of the Early Middle Ages were low population densities, very low urbanization rates, very low literacy rates, and almost zero lay literacy rates. Being in a reference class of times and places with such characteristics, it would be a miracle if any significant progress happened during Early Middle Ages.
China also springs to mind. I have listened to documentary about the Chinese empire and distinctly remember how advanced yet stagnant it seemed. At the time my explanation was authoritarianism.
But 1) I’m not sure anyone has a good grasp of what the properties we’re trying to duplicate are. I’m sure some people think they do and it is possible someone has stumbled on to the answer but I’m not sure there is enough evidence to justify any claims of this sort. How exactly would someone figure out what general intelligence is without ever seeing it in action? The interior experience of being intelligent? Socialization with other intelligences? An analogy to computers?
2) Lets say we do have or can come up with a clear conception of what the AGI project is trying to accomplish without better neuroscience. It isn’t then obvious to me that the way to create intelligence will be easy to derive without more neuroscience. Sure, from just from a conception of what flight is it is possible to come up with solutions to the problem of heavier than air flight. But for the most part humans are not this smart. Despite the ridiculous attempts at flight with flapping wings I suspect having birds to study—weigh, measure and see in action—sped up the process significantly. Same goes for creating intelligence.
(Prediction: .9 probability you have considered both these objections and rejected them for good reason. And .6 you’ve published something that rebuts at least one of the above. :-)

From quote in that post:

Being in a reference class of times and places with such characteristics, it would be a miracle if any significant progress happened during Early Middle Ages.
High and Late Middle Ages on the other hand had plenty of technological and intellectual progress.
I’m much more surprised why dense, urbanized, and highly literate Roman Empire was so stagnant.
China also springs to mind. I have listened to documentary about the Chinese empire and distinctly remember how advanced yet stagnant it seemed. At the time my explanation was authoritarianism.
All that is fine.
