Its like now, when every SaaS company scrambles a way to put AI into their product, just because they think they need to.

I find this view from pg very narrow minded, and borderline ignorant. He is shaping his essay as in the role of higher education and academia is only to produce startup founders. Which is not, it is a way of a state investing into a labor force that is needed. As long as there are large corporate multinationals, there will be a need for finance, economics and yes, even management. Are a lot of that studies fugazi? Sure they are, but so are a lot of startups.

If everyone coming out of academia would be startup-like, corporations and other businesses simply wouldnt have the workforce for their machinery, and then some big shoot CEO would write blogs how Universities Should Prepare White Collars.

And indeed, reading period produced two trillion dollar companies, but this is statistical anomaly. You could just as well argue, that it keps economy afloat by educating up-coming workforce, but thats harder to prove.

He has been like this for a while now. His last few essays are simply advertisement for a startup accelerator. Conveniently, he also owns one of them.

This is not as simple as it sounds. It seems, from my experience of learning a guitar and observing others, that there is something inherently illogical how tonality changes between strings. There are two main ways to do it, either you remember by memory, or you simply hear what happens. Both are hard for average beginner, because it just doesn't make sense.

After I have been practicing a guitar for quite some time I started learning a piano for some reason, and seeing the keys in front of me it all made sense instantly

OP said this, you clearly don't fall into this category. And if servicing an electric car costs more than servicing an old Landrover I will not eat for a week

In Slovenia, a post-Yugoslavian country, the school library coordinated a textbook borrowing scheme, where they would own all the material and lend it to students each year. Parents would pay a small "subscription", so each year or two one subject would get new books.
