M1 16 billion transistors

M5 28 billion transistors

so that would be more like a 4/5 year doubling rather than two years.

That said there's a chart in Wikipedia showing it still going on https://upload.wikimedia.org/wikipedia/commons/c/cc/The_Moor...

but that's calculations per second per dollar rather than transistors per chip like Moore.

More came up with the law in 1965 and thought it would run 10 years till 1975 so it's had a good run if it's petering out now.

The compute per sec per dollar is a longer trend ~1900 that will likely keep on.

Gemini thinks: "The machine that began the long-term trend often cited as "128 years of Moore's Law" was Herman Hollerith's tabulating machine, created for the 1890 U.S. Census"
