I am not saying that it doesn't use something that efectively is a probability calculation anywhere in the system, but that that isn't the main or the most important "engine".
I agree with your comment on "first learning thousands of other concepts". But that is a ton of (hierarchical) concepts that have to bo stored somehow and isn't then the storage/retrieval itself maybe more cruicial to the whole function than any special algo we just haven't figured out yet? (I mention this in my "wild" speculation on "models") :)

Algorithms that do something like this are called Deep Learning and have recently proven extremely effective at machine vision and other tasks. They don't all work by prediction per se but they do learn to compress the input down to a smaller representation of features that can be used to recreate it and are very related to prediction.
