It was a good read on the concept but I’m left unsatisfied by hand waving all the stuff. Like how, physically, is the reinforcement actually saved? Is it a number in a file? What is the math behind the reward mechanism? What variables are changed and saved? What is the literal deliverable when you serve this to a client?

The article isn't what the title say it is, so it's still good despite the title claim being questionable.
