Many users of pytorch are scientists and folks only peripherally interested in software. For them, python scripting is great because of its low barrier to entry. The torch ecosystem is large, and consists of folks like that. They are unlikely to learn things like rust. So, instead of wholesale reimplementation of pytorch, a better bet would be to replace parts of pytorch that are slow and bloated. Those parts would be invisible to end-users, and would be a great candidate for a rust refactor.
