I play tetris too (hkgwife)

In the early days of computer chess people used to estimate that it would be ten years until a computer (or program) was world champion. But after ten years had passed, it seemed that the day a computer would become world champion was still more than ten years away... This is just one more piece of evidence for the rather recursive Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law.
