LLMs have essentially made any language above the C++/Rust systems level tier obsolete. The only reason you picked a language like C# or Python is often out of convenience of having a broad ecosystem or due to the lower level languages being too hard to master, with too many footguns. The tradeoff being is that you got a less performant implement, while being easier to write. Nowadays, those arguments are dead.

LLMs can now write perfect code in low-level languages, that is frankly _safer_ and _exponentially_ faster than implementations in high-level languages.

Your experience does not match mine.

It writes ok code, it does not write good code. I see it leaving a lot of performance on the table, doing silly things like wrapping everything in a global mutex. Or certainly doesn’t write idiomatic code in Rust or C++

Yeah, let LLM write C++ when your team have cannot comfortably write C++ in the first place. This is surely a frankly safter way than human-written C# and Python.

Yes indeed, that will be a much better road to a durable, maintainable, secure and agile product than focusing on product goals in a higher level language with a framework.

When will we start using LLMs to write my web backend directly in UEFI and assembler? (Although uefi is an OS, so maybe more fair to exit the boot services)

Software will get slower as we do things beyond the current hardware capabilities which is always the case as hardware improves.

We have yet to reach the limit of the radius that we already have

I had an Odin code base with raylib doing cpu bound stuff. On Catchy OS it tanked my frame rate from 120 to 90 fps (intentionally, seeing what I can get away with). Same build, on Windows 11, 40fps.

the OS makes a huge baseline difference
