> Finally, we will continue to progressively open-source more of the Mojo language, as well as components in MAX that we have built with it. Our commitment remains unchanged – we will open source the Mojo compiler and toolchain in 2026.

The point is that Mojo compiles to MLIR for programming on heterogenous compute and GPU so something like Pydantic isn't really comparable here.

The alternatives would be stuff like CUDA

The value has already been materialized. They were acquired by Qualcomm for $3.9 billion.

C and C++ were closed source for quite some time, they still are in places like commercial embedded OSes and console dev kits, even when they happen to be GCC and clang forks nowadays.

Clang actually has replaced most GCC forks exactly because vendors can keep the fork closed source.

Pydantic is mainly about making Python strongly typed.

Mojo addresses the actual need to write code in other languages, such as C++ or CUDA, for low level and hardware specific work.

But I wonder if it has already missed the AI hype cycle, when a lot of low level code is being written. I'm not sure how the developer ecosystem will react now.

Their website has a banner suggesting news about open sourcing of the compiler at some Aug 18 convention.

They are going to open source it eventually
