ie "python is scary fast because anyone who uses it is mostly running C"

Yep. This goes for a lot of environments. It's going to take many many decades to get rid of C. Probably more than it has been here up to now.

Doesn't always mean it's particularly performant, unfortunately. The JSON lib in PHP is still C (part of Zend), but it's very susceptible to malloc failures (one big contiguous request for the whole shebang), and it's generally way faster to serialize arrays into a .PHP file you load than into JSON if you're storing it locally. I compared what I read there to the serde stuff for rust and the difference is stark.

Maybe having most of this stuff in c libs with scripts wrapped around them will make it easier to migrate. Keep the same py but swap out the lib from C to some rust that's still useful in a crate for pure rust projects.

what you’re really saying is that C is fast and python is slow. I don’t think that was ever in debate.
