Moore's Law roughly states that we get a doubling of speed every 2 years.
If we're 6 orders of magnitude off, then we need to double our speed 20 times (2^20 = 1,048,576), which would give us speeds approximately in line with 40 years ago. Unless my understanding is completely off.
The rule of thumb is "about a 100000x slowdown". With Moore's law of 2 years that means it would operate at speeds of computers from about 40 years ago. Although really that's still making it seem like it's faster than it is. Making direct comparisons is hard.
