Mojo looks extremely promising. Lattner has some hits and misses but in general I find myself agreeing with him on principles. A brief skim of MLIR is interesting as well and I can understand it's goals and how it fits into the LLVM ecosystem. Python is is a pleasant language to use and it has a massive and growing ecosystem. This combination of a stellar tech leader, a clear defined technical goal built within and on top of an existing powerful compiler platform/framework, a popular and beautiful language foundation including a huge library of existing performant code, and impressive performance claims - this all adds up to something worth paying close attention to. Some random thoughts: After watching tutorials on PyTorch I've come to the conclusion that new programming languages must have syntax built in for dealing with tensors/matrices. The flexible array index syntax in Python allows for some nice ergonomics for this but I have a feeling that we are just scratching the surface. I understand that they don't have a public release nor a license - but I would like some more clarity on this before becoming more invested. Just saying "open source sometime soon" is a bit vague. I worry about the eventual divergence these kinds of projects make from their source. Inevitably there will be a day when Python moves in a new direction that won't be compatible with Mojo. Will they remain tethered to Python on that day or will they feel sufficiently independent to go it alone? I was very excited by Swift as a language. I was excited when Apple open sourced it. I was excited when Google was using it for TensorFlow. But it feels stalled out somehow. I don't understand the dynamics of language growth and adoption well enough to make predictions. If I were to start a new ML company today I don't know how comfortable I would be choosing Mojo over Python. Just having the current backing of a business will not guarantee success. Will this language offer enough to attract Python, C++, Rust, Julia, etc. devs over? They talk about deployment story ... but there is competition there as well in things like WASM. There are more ways to fail than there are to succeed - and I wish something like this would succeed but reality is so fickle.
