Maybe I'm a party pooper, but given Qualcomm history, open sourcing just after acquisition feels like they don't care about it and they're going to let it die while they cut Modular in pieces and extract all the juice possible of their cloud offering.

Open sourcing was on Mojo's roadmap long before Qualcomm was in the picture.

close source language is a dumb concept anyway

Qualcomm is a notoriously closed source company. Don't reward them with your support just because they are forced to open source something.

They are no better than Nvidia. I do not see your point.

Did you mean “worse”?

No need for snarky comments. These days tools/frameworks/languages/libraries/etc are popping all the time. Do you expect people to research every simple signal they catch in the wild?

I'm glad that it's open source now and they are supporting a lot more hardware. There are some interesting features that I hope the language design community pays attention to.

It's built on top of MLIR so you can make compiler optimizations in a library instead of the compiler. I believe Reactant.jl has been using MLIR for optimizing higher level abstractions in Julia. Imagine a Lisp with that capability.

Exciting. For hobby projects, I was looking into what should be my programming language. Open source was a criteria. Now I have choice between Rust and Mojo.

What sort of projects are you looking at doing?

Julia is extremely lispy in its semantics and design, it's mostly separated by syntax.

Qualcomm is changing a lot. They are learning and adopting open source. I’ve seen this in other Silicon vendors, they used to deal only with big corps and would talk to you only if you promised to buy millions of parts. Now they are all moving to a model where they want an open ecosystem , attract developers, promote open source. It’s changing , it’s not going to be perfect, there will be false steps but the direction is good and we all benefit from this change. As someone else said they are way ahead of NVIDIA in open source adoption so you should keep an eye on Qualcomm

NVIDIA is way worse and QCOM are improving

If anybody wants to give a talk on this at the 2027 Carolina Code Conference, our call for speakers will be open from January to March. Love featuring languages like this.
