like all of the legacy quantum chemical and FEM codes or anything else you run in HPC (which are a lot of codes, which are not ported from one day to the other by an army of self-declared ML-pros). Part of them can be GPU-accelerated, but then you can easily eat TBs of memory with the right system and GPUs still have a way to go there.
