If Python devs/users had to actually use all pure Python libraries, no C bindings or Rust bindings, no RPC to binaries written in faster languages, it would get dropped for a ton of use cases, absolutely including its most prominent ones (machine learning, bioinformatics, numeric analysis, etc.).
It would probably especially include those before most others. The best thing about Python IMO is the FFI and the ecosystem built around it.
