Isn't that XZ?

  No. It is an unrelated algorithm.

    It's a very strange algorithm completely different from most compression methods, that's what makes it interesting IMO. But it's probably not realistically competitive, since one needs to do more after the burrows-wheeler transform, and all that "more" has been ridiculously more optimized in zstd and other modern compression methods. Compressing bwt-transformed data is easier, but that doesn't mean it's easy to further than what's easy.

      I saw bellard neural net compression benchmarks. If you have time and performant system, based on the semantic of the data to compress, neural net seems tough to beat. It is a matter of good compromises: speed and efficacy. I even wonder if LZMA2 is worth replacing bzip2.

  You're probably thinking of LZMA2.
