David Beazley's PyCon India closing keynote, in which he live-codes a stack machine and grows it into an interpreter that runs WebAssembly, then uses it to play a Rust-written game. It requires no prior WebAssembly knowledge.

Miguel de Icaza's GodotCon 2023 talk on Swift bindings for Godot. He argues that garbage-collector pauses in C# are a persistent problem and that Swift's reference counting avoids them.
