"The performance of a personal computer (PC) today is the same as that of a supercomputer 20 years ago"

After hearing the story, I did some calculations.

- After 2000, the performance difference between PCs and supercomputers have been roughly 10,000 times

- Moore's Law "doubles performance in 18 months."

Given that from the information,

Solve 2^(x/1.5) = 10000.

x = 19.93 years

I see, 'We are all using 20-year-old supercomputers'.

In other words, in theory, as of 2003, weather forecasts and earthquake prediction calculations that were being calculated on supercomputers can be done in your own room.

From my point of view, 'I just have to wait for 20 years'.

Conversely, the cost of development and investment in supercomputers (about 130 billion yen, not including maintenance costs) is in this '20-year leading'.

I don't know what you all think, but I think the cost is generally reasonable.
