Fun fact: there was a future type in the rust standard library, long, long ago.

That version of Rust also did async I/O in the runtime. Async I/O has always been part of Rust. The model changed because there was too much overhead doing it the more ergonomic way and it got booted out of the runtime.

Yep, this is a great point.

Someday, we should get a book about the history of Rust together...
