Interesting read, although I don't agree with everything. I like the distinction between different qualities of abstractions, made in the beginning. The following bashing of abstractions is too generalized for my taste.
The best part comes close to the end:
> Asymmetry of abstraction costs
> There’s also a certain asymmetry to abstraction. The author of an abstraction enjoys its benefits immediately—it makes their code look cleaner, easier to write, more elegant, or perhaps more flexible. But the cost of maintaining that abstraction often falls on others: future developers, maintainers, and performance engineers who have to work with the code. They’re the ones who have to peel back the layers, trace the indirections, and make sense of how things fit together. They’re the ones paying the real cost of unnecessary abstraction.
