A humble Rubik’s Cube has proven that AI isn’t always best at performing computational tasks.

Researchers from the University of California developed an AI system capable of solving a Rubik’s Cube in 1.2 seconds.

That sounds impressive – and to us mere humans it most certainly is, with the world record at 3.47 seconds being held by Yusheng Du – but the AI solved the Rubik’s Cube around three times slower than the fastest algorithm not trained using a neural...
