> Why not develop Mojo in the open from the beginning?

> Mojo is a big project and has several architectural differences from previous languages. We believe a tight-knit group of engineers with a common vision can move faster than a community effort. This development approach is also well-established from other projects that are now open source (such as LLVM, Clang, Swift, MLIR, etc.).

Given Chris Latners previous achievements I think we can trust this call a bit more than we may with some companies.

I wouldn't use it myself until open sourced.
