I only have this screenshot to go by and I can't be bothered looking up the article, but it wouldn't surprise me that that these things appear to get dumber the more you try to cram them full of information because they have no actual intelligence to parse all that data - it's just looking for patterns. This is intelligence as defined by the "97% of scientists agree" crowd.

But hey - the fact that they've managed to build a computer that can't do maths is an incredible achievement in itself.
