FTFA:

So we have two basic options: pay for bigger hardware, or spend more time writing/maintaining custom code that allows us to live on our existing hardware.

Hardware is Cheap, Programmers are Expensive:

Given the rapid advance of Moore's Law, when does it make sense to throw hardware at a programming problem? As a general rule, I'd say almost always. Consider the average programmer salary here in the US. You probably have several of these programmer guys or gals on staff. I can't speak to how much your servers may cost, or how many of them you may need. Or, maybe you don't need any--perhaps all your code executes on your users' hardware, which is an entirely different scenario. Obviously, situations vary. But even the most rudimentary math will tell you that it'd take a massive hardware outlay to equal the yearly costs of even a modest five person programming team.

From someone who's a published author, I expect better grammar in a book review.

That's what editors are for. In real life, good writers may be horrible at proofreading their stuff, but be excellent at connecting with their audience and expressing things in an easy to understand and entertaining way. As one of my professors said in a writing class, "Grab your readers by the eyeballs!"

(Far be it from me to criticize your Grammar Nazi ways; I'm with you the whole way. I did, however, want to take issue with that one sentence.)

When this book/review demonizes "chiropractic... medicine", it's talking about chiropractic methods that supposedly cure, for instance, your liver or high blood pressure. It's not talking about what a Doctor of Chiropractic (DC) does that demonstrably, scientifically, and certifiably puts your bones where they are supposed to be rather than where they aren't supposed to be (this is, quite obviously, a problem that needs to be fixed). The former is quite unproven by studies, while the latter is proven not only by studies, but is also shown logical by an 8th grade biology class. The former is an "off-label" use of the latter. Your injury/cure appears to have been the latter.
