The main point is as technology advances, it starts to accelerate rapidly (nearly exponentially).

If we developed a super AI that is 1x our intelligence, within a short time it will be 2x, then 10x, then 50x, then 1000x, and so on.

The chart represents the entire timeline of the human species. If you think about it, most of the real technology we have developed has been in the last couple hundred years.

As a species, we have been around for 315,000 years, but only the last 50,000 years represent what you would consider modern man.

The amount of technology and advancement in the next 100 years will dwarf the first 50,000 just like the next 5 years will likely dwarf the last 20-50. The relationship between those numbers over time will get even more ridiculous.
