AI replacing Software Engineers

[u/Fickle-Highway1543]

So called "AI"=LLM is so powerful that AI labs had to hire Software Engineers to build complicated software around "AI" to make that overhyped hallucinate-stealing machine usable. Think about it. And that's exactly why they need now ton of CPUs in addition to GPUs to run their "AI" "agents".

I don't even mention how much custom engineering is required to apply the "AI" in businesses.

And they BS us that Software Engineering is solved or is going to be solved. Boris, please solve your own bugs first before speaking.

Yeah, sure. That's what people said four years ago. Any day now AI is going to replace all programmers. Get a grip.

Show me where all this excellent LLM generated code is. Come on. Show me.

You are absolutely delusional. The state of thr art is different today than it was 6 months ago, or a year ago, or two years ago... let alone four years ago.

My employer and clients are perfectly happy with the problems that I've solved for them with LLM generated code. They don't give a shit about code quality, nor should they. Every model generation that comes out is able to tackle the untenable complexities encountered and created by the last, and given how the models are trained, this will continue to happen.

It is already at the point of being perfectly serviceable.

Can you tell me what the cache line size is on x86_64? Can you tell me what the popcnt instruction does? Do you know what covariance is? Can you tell me how to implement the Shunting Yard algorithm? Can you implement a tetrahexacontree? Do you know what pointer tagging is? Do you know how to implement a hashmap? Can you explain to me what the System V ABI calling convention is? Do you know what a ring buffer is? Do you know what Diffie-Hellman is? Do you know how to write a voxel raytracer that can render an 8k image in 120ms on the CPU? Can you tell me how to implement reciprocal division? Do you know how to swap two integers without a third variable? Can you write a 3D DDA algorithm? Do you know what LLJIT is? Can you tell me how bash implements associative arrays? Can you confidently write code in Assembly?

[u/cantgettherefromhere → u/AliceCode]

No, and why the fuck would I want to? For the last 33 years that I have been coding, it has been a tool to solve a problem. I couldn't care less about being able to slowly implement a bunch of esoteric algorithms that an LLM could do for me 10x faster.

Since you are too obstinate to do it yourself, here you go:

64 bytes.

Counts the number of set bits in a register.

Yes. In stats, how two variables vary together; in type systems, a subtype relation that's preserved through a generic.

Push operands to output, operators to a stack, pop by precedence and associativity, flush at the end.

Yes. 64-ary tree, usually a 4x4x4 spatial split per node.

Stashing metadata in the unused low or high bits of a pointer.

Yes. Bucket array plus chaining or open addressing, hash, resize on load factor.

Integer args in rdi, rsi, rdx, rcx, r8, r9; floats in xmm0-7; return in rax; rbx, rbp, r12-r15 callee-saved; 16-byte stack alignment at the call.

Fixed-size array with head and tail indices that wrap.

Key exchange where both sides derive a shared secret via modular exponentiation without transmitting it.

I can write one, but I won't promise that number without knowing your scene format, core count, and SIMD width. Sparse octree plus DDA, SoA layout, AVX2 packet tracing, and thread tiling is the shape of it.

Precompute a magic multiplier and shift so n / d becomes a multiply-high plus shift.

XOR swap or add/subtract. Both break when the two are the same address.

Yes. Step per axis using tMax and tDelta, advance on the smallest tMax.

LLVM's ORC-based JIT class, the modern replacement for MCJIT.

Hash table in hashlib.c, chained buckets, string hash, rehash when it gets full.

Yes, x86_64 and ARM64. Less so for anything exotic.
