If it was the easy part, then why did they pay us hundreds of thousands, sometimes millions, sometimes more - to do it? The fact of the matter is that it wasn't easy, not for a brain that's architected the way a human's is. The fact that computers can now do it much more quickly and arguably - in many cases - better doesn't diminish the act itself - it just shows how far AI has come, and how easily human intelligence will be dwarfed as it continues to make progress.
