Buck2: Our open source build system

> Buck2 is an extensible and performant build system written in Rust

I really appreciate tooling that is written in Rust or Go that produce single binaries with minimal runtime dependencies.

Getting tooling written in for example Python to run reliably can be an exercise in frustration due to runtime environmental dependencies.

Personally it seems like a huge waste of memory to me. It's the electron of the backend. It's absolutely done for convenience & simplicity, with good cause after the pain we have endured. But every single binary bringing the whole universe of libraries with it offends.

Why have an OS at all if every program is just going to package everything it needs?

It feels like we cheapened out. Rather than get good & figure out how to manage things well, rather than driver harder, we're bunting the problem. It sucks & it's lo-fi & a huge waste of resources.

You’re probably thinking of static binary. I believe that OP is comparing a single binary vs installing the whole toolchain of Python/Ruby/Node and fetching the dependencies over the wire.
