Python is not perfect and languages do evolve. Maybe Rust or Go or something new will take over the world. But there's a trade-off between developer time and execution time and you can't focus on just one. There's also the benefit of a large ecosystem of libraries (and talent, if you are a large enterprise) when you embrace Python that may not yet be available in some other newer languages. Prototyping usually involves working with existing code base and the ecosystem, although if you are building a brand new product or application, your context may be different.
