While impressive, it isn't really about wits or smarts.
The AI has much faster reaction time not because it is smart, but because there is zero lag. The game is more than just anticipating your opponent, but has a lot to do with making things simultaneously fast.
Look at how the pro play, measuring in keys per second and how fast they move their view point from one area to the other.
They can't compete with an AI that can look more than a few areas simultaneously because it can switch to one area, and it already knows that is going on as it moves to the next.
It is like a great tactician who plays at 10 clicks per second vs a decent one who plays at 200. Even if you are great, you can miss something out just because you looked at it 2 seconds too late, which doesn't happen to an AI.
