How does having a working knowledge of concepts like files, or using a command prompt, equate with having to learn the guts all the way down to Maxwell's equations?

Much of the scenarios this dude mentions are table-stakes in the grand scheme of computing things.

Instead we have an endless supply of wanterpreneurs re-engineering everything to make computing as mindless as possible because everyone knows the stupider it is, the bigger your potential audience is. And since everyone wants megagrowth bullshit we have to make using a computer as dumb and mindless as possible! Fuck all the people who take the time to understand this stuff, who got these companies to where they are today, they are the long tail...
