>It's that in some scenarios python can't be made fast. Can you give some examples of this? I mean, obviously with enough effort you can "make python fast" since it has good C bindings, and can just be a thin wrapper around fast stuff. Similar to how command line tools can be ridiculously fast[^1] despite, ostensibly, running in bash. So I'm a bit confused about what you're claiming. Organizational issues, it's difficult to get management on board with an optimization pass?
