Where are the old programmers?<p>But they never existed in the first place!<p>The programmer population doubles every 5 years (approximately).<p>So even discounting the age pyramid (dead people, or career changes),
there are only 0.20% of 60-64 year-olds, vs. 50% of 20-24 year-olds.<p>0.20% 60…64-yo,
0.39% 55…59-yo,
0.78% 50…54-yo,
1.56% 45…49-yo,
3.12% 40…44-yo,
6.25% 35…39-yo,
12.50% 30…34-yo,
25.00% 25…29-yo,
50.00% 20…24-yo.<p>That adds up to 6.05% of 40-64-yo vs. 93.75% of 20-39-yo.
There never was enough programmers to make old programmers.<p>Of course, we cannot stay on this exponential growth long, so the question will have to be revised in 20 years; then we'll see what happens of all those young Amazonians :-)
