      - For many languages, we can get away with Untangled LP. See, e.g. https://quotenil.com/untangling-literate-programming.html

      - Introducing redundancies (of code, tests, documentation) is our primary tool to increase our confidence in the correctness of the solution: See, e.g. https://quotenil.com/multifaceted-development.html

      - Untangled LP has been a good idea even before LLMs. It's even better now, as LLMs can maintain documentation and check it against the code.

      Regarding the GPU, you might find an interest for MGL-MAT[1]:
      "MAT is a linear algebra library for working with multi-dimensional arrays which supports efficient interfacing to foreign and CUDA code. BLAS and CUBLAS bindings are available.". The author's blog is quite interesting to read (see for example [2]).

      Can't believe this Reddit quality comment is getting any upvotes. Google AI Challenge is "Yet Another Contest"? Though you may not be surprised, he is, http://quotenil.com/Planet-Wars-Post-Mortem.html/.

      Here's the post mortem by the winner of the subsequent AI contest: http://quotenil.com/Planet-Wars-Post-Mortem.html
