Buck2: Our open source build system

> Build systems stand between a programmer and running their code, so anything we can do to make the experience quicker or more productive directly impacts how effective a developer can be.

How about doing away with the build system entirely? Build systems seem like something that shouldn't exist. When I create a new C# .NET app in Visual Studio 2019, what "build system" does it use? You might have an academic answer, but that's beside the point. It doesn't matter. It just builds. Optimizing a build system feels like a lack of vision, and getting stuck in a local maxima where you think you're being more productive, but you're not seeing the bigger picture of what could be possible.

How do you think VS builds your code?

The point is it doesn't matter. What it's doing internally isn't interesting to me, a programmer. I'd rather not think about it. Unfortunately, people have decided that microoptimizations like writing declarative build definitions by hand is beneficial, so I've had to learn many build systems.
