while I don't disagree that currently JAX outshines Julia's autodiff options in many ways, I think comments like this are 1. false 2. rude and 3. unnecessary to make your point
Anything particular in mind?
- I wrote this elsewhere: I find their approach to memory management/mutable arrays really hits the worst of both worlds (manual memory management and garbage collection). You end up trying to preallocate memory but don’t actually have control over memory allocations. I find the dynamic type system exacerbates this.
- It’s a very big language, even in the IR. So proper program transforms like mapping functions or autograd are quite difficult to implement.
- Static compilation is really hard, which makes it a non-starter for a lot of domains where it could have made inroads (robotics, games, etc).
