> People abstract before an abstraction is necessary.

Sometimes an abstraction cuts to the core of the reason why.

See for example https://algebradriven.design/

Good abstractions can communicate intent better than mounds of concrete code because they speak at a higher level.

However, mounds of okay concrete code is way easier to deal with then poorly thought out abstractions.

This means pragmatists get little practice in abstractions, where their pragmatism is needed most to uncover the useful abstraction and avoid the overly complex invented abstraction.

Abstract code also has the advantage of parametricity in strongly typed programming languages.
