Doing ffi from c to python is easy.
From rust to python is annoying. Have to use unsafe, and weird parts of the rust stl. funky refs. Random crashes! oi vey.
The followup question is "Is it easy in C because it's actually easier or because the result is code that has a half-dozen hidden undefined-behavior mines that C does a poor job of detecting at compile time?"
Rust isnt safe across the ffi barrier, so its not a fair criticism of c. go check it out.
