Known entities are recurring patterns (we give names to things that occur more than once, in the world or in our thoughts). Concepts are recurring thought patterns. Abstractions, relations, metaphors, are all ways of finding and transferring patterns from one domain to another.

Sure, I understand what the terminology means but I don't believe we get to AGI without some ability to translate the learning of say using a mouse to using a trackpad in a simple way. Humans make these translations all the while, you know how to use a new room and the items in it automatically but I personally see the systems we have built are currently very brittle when they see new environments because they can't simplify everything to its fundamentals and then extrapolate back to more complex tasks. You could train a human on using an Android phone and give them an iPhone and they would do pretty well, if you did this with modern machine learning systems you will get an extremely high error rate. Or say you train an model on how to use a sword, I'm not convinced it would know how to use and ax or pair of crutches as a weapon.

Maybe it will turn out to simply be enough artificial neurons and everything works. But I don't believe that.
