Why are there high level languages?

Why the hell would anyone use Python or Ruby over C. The software should be nice to use. It's not nice when the program is slow as fuck.

Their dynamic nature makes debugging software increasingly hard. Basically developing with these higher level languages takes more time than with C.

Every program should be written in C. In most cases, it would be good to also optimize tight loops with Assembly. This way programs would be fast and fun to use.

Languages such as C# and Java have no point at all. They are essentially crippled versions of C. Limited pointers and limited memory management. The virtual machine takes forever to JIT-optimize the code, thus harming the user experience. Not to mention GC, which slows everything down, providing nothing useful in return. GC is shit.

Then there are these C++-retards. Sure, you can in theory make as fast C++-code as C-code, but is it really worth it? Every C++ program in practice is slower, harder to debug, and harder to develop.

Functional languages, such as Haskell are no answer to problem. They abstract the hardware to hell and are very slow in practice.

So tell me: Why is C and Assembly not used for every program today?

usually leads to more secure programs

That could actually be a bad thing. Unrootable/unjailbreakable devices with DRM, only the corporate brainwashed drones would love that shit.

it would suffer from the same things if it was made in C

because its design (or lack of thereof) has a much bigger impact on the end result. like orders of magnitude greater.

That's the point. C makes it a lot harder to add bloat. You can write one line in an HLL that'll take a few thousand to implement in a lower level language. That tends to make you reconsider whether you should do anything and cause you to come up with a simpler solution. It's possible to write bloated code in C or even Asm, but you have to try really, really hard to.
