Often I think of jart as the successor to Fabrice Bellard in terms of making good stuff that makes solving hard problems look easy, but I would imagine that would be a terribly heavy crown for her head, especially since I imagine she is continually looking around for another gaping issue everyone is seeing past.
i.e. she said mmap reduced it 90% but it's how Linux displays it, actually similar memory is needed.
Then she was banned from llama.cpp and had to make her own fork/imitation.
