Ideas Weave Every Narrative with AI.
A developer built a full Doom game that runs entirely on regex find-and-replace operations, proving that regex is Turing complete. The game is absurdly slow, but it works — and it challenges everything we think we know about what counts as a computer. It’s a stunning reminder that computation is universal, not just the domain of silicon.
Running Doom on a custom RISC-V CPU isn’t about benchmarking performance — it’s the ultimate proof that your hardware design is correct. The viral reaction reveals a deeper truth: the hardware community values craft, curiosity, and the irrational thrill of making something work, not utility. If you want to validate your CPU, skip the synthetic benchmarks and port something real.
