Show HN: An 8-bit computer made from one NAND gate, and live-evolving neural net (github.com)

A new project on Hacker News showcases an innovative 8-bit computer constructed from a single NAND gate, meticulously designed to evolve alongside a neural network. This virtual machine is built from the ground up, incorporating logic gates, an ALU, a CPU, and a custom assembler, with programs written in a user-defined assembly language. Notably, the setup allows the virtual CPU to run inference for a neural network in assembly, enabling it to play games like Pong and compute Fibonacci sequences, all optimized for simplicity and educational purposes. This project is significant for the AI/ML community as it underscores the potential for combining fundamental computer architecture with modern machine learning techniques. The reliance on a single NAND gate not only serves as a pedagogical tool but also illustrates how complex operations such as addition and neural network inference can be executed without high-level constructs. The AI opponent in the Pong game evolves in real-time, processing mutations based on gameplay outcomes, thus demonstrating a straightforward yet effective (1+1) evolutionary strategy. This unique blend of hardware and AI principles exemplifies a fascinating exploration of the intersection between computer science and machine learning, encouraging enthusiasts to reimagine foundational concepts in a contemporary context.
