I've no clue what you just said :) Modeling the business domain with types that match it is table stakes. Otherwise you end up with a "stringly-typed" codebase in which everything is just a primitive type. This and the issues

None of that qualifies as magic. Indicators of magic features are implicitness, action-at-a-distance, high complexity.

From what I've heard, most crash testing focuses on car-on-car crashes, instead of car-on-pedestrian. The inevitable result is big and fast cars efficient at killing pedestrians.

Right, but the problem is, it's unsafe to rely on sound in this manner to begin with, regardless of car noise levels. Sound can only be used for positive identification - if you can hear a car, it's there. It cannot be used for

There's a key relationship you're missing here. The closer a car is to humans, the slower it will drive. The slower it drives, the more important engine noise is. A car going 50km/h+ is on some sort of a highway, where noise

That is true in the pragmatic sense, those who only use C for its objective qualities would find Rust a good replacement. However, those who use C because they like the language would not enjoy Rust one bit and would much prefer Zig over it

Stress is caused by lack of control, in this case due to the inability to predict, and therefore affect, an outcome. A good example is driving, controlling a vehicle at speed necessitates constantly making accurate predictions. People get c

I've noticed this effect when learning to play a game. In order to improve, one must practice a skill, but one cannot do so if they don't have an idea of what a better way to execute that skill is. Therefore, a certain amount of t

You'd think so, but from what I've seen, the overlap between enjoyers of Go and Java is tiny. The languages may occupy the same niche, but their design philosophies are at opposite ends of the spectrum.

It doesn't matter. What does is Go 1.0 shipped without generics. That single decision immutably affected the entire language. Now that generics have been retrofitted, the issues are clear as day: - Awkward transition period between a s
