Please don’t eat my RAM. I need it for mining MemoryCoin ™.

There are two many programming languages and frameworks. There is a lot of doubling. Why the heck is there Dart/Flutter? Just use Javascript/TypeScript. Why Swift, when you have D, Go, Rust, Python with type annotations, etc.? In my opinion, just too much waste. Of course, in a niche, like OS development or embedded, there can be actually a need for hyper optimized special solutions. But the “mainstream” rest?
