I think his point 1 is underrated. CS degrees are flat because aptitude is flat.
You can compare CS degrees to other degrees over time at nsf.gov:

We have more grads than ever, but they are dumber than ever (we have the data to prove this), getting less difficult degrees.
I have a bad feeling that we are running up against some diminishing returns on education and hiding it with numbers like the total number of grads. The number of grads for difficult degrees and the quality of grads seems to be another story.
> In 1970s 1-in-2 college grads aced Wordsum test. Today 1-in-6 do. Using that as a proxy for IQ of the median college grad, in the 70’s it was ~112, now its ~100.
