The exchange drew 7.1 million views; the top reply says compilers work because their output is deterministic.
Why now: The compiler-determinism rebuttal is still the top-voted reply in the r/singularity thread breaking down Musk's claim.
Musk told a Tesla engineer that source code is becoming like assembly, disposable once AI writes the program, per an exchange on r/singularity. He was replying to the engineer's line: "I might never look at the source again."
That's a bet against code review, diffing, debugging, and audits, the checks that keep software safe to ship. The reply drew 7.1 million views, and the r/singularity thread breaking it down pulled 738 comments of pushback.
The top-voted reply lays out why compilers aren't a precedent. Their mapping from source to assembly is deterministic: the same code always compiles to the same output, and every step is inspectable. Skip the source, running a stochastic model instead, and you lose the ability to review, diff, or debug the result. Auditing goes too, along with porting the code across chips like ARM, x86, wasm, and RISC-V.
That rebuttal is correct, but it dodges the harder question. Say English prompts become the artifact engineers actually keep and edit. If those prompts must get precise enough to make a model reliably produce the same binary twice, they stop being English. They turn into a programming language with syntax, versioning, and code review, wearing a prompt costume.
Musk isn't describing the death of source code. He's describing where the next one gets written.
What I'd want to see before buying the pitch is a team shipping production software from prompts alone, no readable intermediate form. Six months later, are they still patching it without falling back to reading the generated code?
