Fable's megakernel submission shows AI systems generating production-quality machine code that outperforms human-written implementations on standardized benchmarks. This creates a compounding dynamic: AI tools handle increasingly complex optimization work, freeing engineers to abstract further up the stack, which generates more training data for the next generation of code-generation models and accelerates automation of R&D. The stakes aren't GPU kernels—they're the hollowing-out of mid-level engineering work and the concentration of technical leverage among teams that can afford to integrate these tools into their development pipelines.
