There's no magic necessary. TFA highlights the exact mechanism by which markets can fill a gap or need via entrepreneurship when incumbents fail to deliver what customers want. It's not guaranteed to happen or work in every case, but there's money to be made by giving people what they actually want.
It'd be like copyright trolling the Library of Babel. The set of useful programs would be totally eclipsed by incoherent gibberish (even if there were a means to ensure that the randomly generated code were syntactically correct). In other words, the signal to noise ratio would be microscopic and running this scheme in finite time would effectively result in zero valuable code being successfully squatted.
I really like the range memorization tool from GTO Wizard, but want to be able to put in custom/arbitrary ranges to test. I also want to be able to import and simplify ranges from other sites. Work in progress, but every scenario is url encoded (warning: subject to future breaking changes) and I use those urls in for links in my Anki decks.
It appears that the phrase has multiple uses/meanings, with priority of definition going to Dunning & Kruger as far as I can find.
This is the earliest clear definition in the sense I was recalling that I can dig up:
"In its place would be substituted the concept of partial radical ignorance. The adjective “radical” is here meant to distinguish this kind of ignorance from the neoclassical concept of rational ignorance, which refers to a state of affairs in which knowledge exists that would improve our situation but that the expected cost of acquiring it exceeds the expected benefit. We thus choose not to know what is not in our interests to know. In contrast, radical ignorance refers to our unawareness of even the existence of relevant knowledge that we could know at zero cost."
I'll concede that this usage is highly niche and lesser known, but I'll have you know that I'm wholly incapable of appreciating irony and will never fully acknowledge my error.
