pbhjpbhj's comment doesn't have a reply link for some reason so I will reply here. Left to their own devices computers will play crude simple development moves in the opening. That's because there are no tactics until the pieces come into contact and it's all strategy, where humans still have an advantage. Decades of experience have resulted in a corpus of classic subtle opening strategies that the computers don't rediscover - for example in some Kings Indian positions Black has precisely one good plan - a good human player will initiate this plan with move ...f5 automatically - an engine will juggle ...f5 with a bunch of other slow moves, (all of which are irrelevant) and might not play it. If you look through the pages of "New In Chess" magazine you will see the top masters analysing their games and saying things like - "The computer does not understand this type of position - it rejects $some-good-human-move but eventually when you lead it down the right path it changes its mind".

All of this is not to say that computers have not overtaken humans in chess. They have. But primarily because they have superb qualifications as practical players - they never make crude errors and all humans on occasion do. This trumps all other considerations. But the vast gap you see when comparing the human lists and the computer lists is exaggerated - 500 Elo points means a 95% expectation. I am 100% convinced that if Magnus could be properly motivated (think big $$$ and somehow convincing him that scoring a decent proportion of draws as White would be a "win") he could deliver for humanity :-)
