Python vs C: Machine learning

I feel like Python is a very stupid choice for machine learning, C is a much better alternative because there's many libraries already available for it, and if not you can make them yourself. Machine learning is mainly mathematics, which C is efficient at, and if you're working with large numbers you could use a bigint implementation such as GMP. I don't get why people choose Python for such intensive tasks, yet choose something like Rust for backend web development, it just makes no sense. Backend doesn't need the best performance, and high level features in that sector are great, while performance and low level control in case of C for machine learning models can be great for optimization, performance, and efficiency for the model. It's so stupid, it's 1000% not worth the syntax sugar, high level abstraction, mathematics integration, and all that when stuff becomes like 6000000 times slower, and not as if mathematics from Python can't be ported to C, they can, and very easily, so like wtf, lol.
