Why I built a Rust deep learning framework (and what I got wrong twice first)

The Python script that made me give up. It had more boilerplate for freezing and re-composing submodules than it did for the actual model. I'd already pivoted three times. The next pivot was going to cost another rewrite. That's the day I decided to build this in Rust. I should say upfront: before this, I had never trained a deep learning model. The path to here was unusual. A theoretical physics degree (with a PhD grant I turned down), then a long detour through documentary film and independent
