In general, I’d say there’s too much superficial flexibility but not enough control. - 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).
