That would mean performence more then doubled on a yearly basis.
How do you figure? They were released 30+ years apart. 2^30 would be a billion times faster. Instead it's something under 19 doublings, nowhere close to doubling every year for 37 years.
There are a lot of different ways to state it (often including constraints like price), in part because it's not really a 'law'. But the main thing is, 500k times performance does not represent 'more than doubling' performance on a yearly basis as this comment claims.
