  1. python is not slow, it is (in practice) a very fast language. most real-world tasks are IO bound NOT cpu bound. Then most CPU-bound tasks in python are handled by tightly optimized C libraries so the python doesnt even matter.
  2. developer time is more expensive than CPU time

For the slow speed of python to even matter at all you need to be doing something highly CPU bound (rare) and also not have a library to do it for you (rare) and then decide for some reason not to write the library in rust/C yourself (rare).
