When readability is highly valued, the readership falls. If it looks complex, it must be hard, right? So people get a sense of personal satisfaction from mastering the apparently complex, even though it is semantically quite trivial.
All experience has taught us that solving a complex problem uncovers hidden assumptions and ever more knowledge, trade-offs that we didn’t anticipate but which can make the difference between meeting a deadline and going into research mode for a year, etc.
If C++ were used only to solve known problems with known solutions, it would be a perfectly OK language. Smart people would design classes “once and for all” and sell them like nuts and bolts, companies could pre-fabricate parts that fit together because of industry consensus on standards and specifications, and this age-old “dream” of some software engineers.
I believe this is a completely insane view of programming, but C++ cannot have any other – it is designed to be an “ex post facto language”
