At the Wolfram Technology Conference 2023, I gave a talk alongside Tom Wickham-Jones — the lead developer of the Wolfram Compiler — on the compiler’s latest advances and directions.

The Wolfram Compiler converts Wolfram Language code into machine instructions that run directly on the CPU, enabling significant speedups and opening the door to new programming capabilities. My part of the talk starts at 42:10 and runs for about 30 minutes, focusing on interoperability: how to call external code from within the compiler — external libraries, Wolfram Language kernel code, and the FFI (Foreign Function Interface) functionality that makes it all possible.
