John Carmack's arguments against building a custom XR OS at Meta

Love to hear whether you agree or not and how your project is different?
Pros: it's fun
Bad for business, good for hobbyists.
It's kinda hard to have a single answer for this but we like to think that this project did not work out for META particularly. We believe that it was perhaps not the right project for someone like META who already had other on-going projects to deal with. Although a setback, it doesn't necessarily mean there's a fault in the idea itself. We'd like to address the problems that were mentioned with the development of a custom XROS -
1) Cost : We've managed to do everything up until this point at the cost of 0$. However, we're in initial stages and expect to incur costs in the next few months. But those costs are mostly associated with building the company and our own line of products, not in the actual development and engineering of the OS. We've managed to remain extremely cost efficient and intend to continue that practice.
2) Burden on third-party/new developers : We anticipated this problem right when we started building the OS. Over time, we've come up with plans to encounter it and are currently working on making sure that the barrier to enter and create applications and software on Xeneva remains as non-existent as possible. We intend on making the process easy, try to bring no learning curve whatsoever, thus allowing developers to port their existing software and applications to XenevaOS conveniently. Also create a beginner friendly environment so that new programmers are able to create an app on XenevaOS from scratch easily.
Cool idea to use your own kernel though it does sound like you could find yourself in perpetual development hell. And, don't forget all the sufficiently powerful SoCs are super closed. You won't be able to leverage any of their existing driver work and you will need some serious clout to get access to their documentation, with some really scary NDAs attached. However I'm sure you know this and took it into account. Very cool. I hope you will manage to get it to market!
Coming to the "vids or it didn't happen" feeling, we totally get that as well. To be fair, we would've had the same feeling if we watched ourselves from a third person perspective. But we're actively working on bringing visible proof (benchmark is a better work) on the claims and promises that we're making. And in your analogy, the vids are coming soon, stay tuned ;)
We've scheduled a prototype launch later this year. We would make much more progress till then and the public would get proven answers from our side once that happens!
This is kind of a non-answer, no? What baggage does it get rid of? What kind of performance optimization does it bring that cannot be fulfilled with an existing OS/kernel?
We intend to plain a clearer picture with proven results of what we're doing in the coming few weeks and months. Stay tuned!
Stay tuned for our Public Beta/Prototype showcase scheduled later this year!
Saying “we’re removing legacy baggage” sounds nice, but it’d be more convincing if you could point to concrete examples where existing systems like Linux actually get in the way. Otherwise this risks becoming a never-ending side quest instead of a platform people can realistically use.
Also you're right in one sense about how building a new kernel from scratch may not be the best way to tackle XR. But our whole point in creating this kernel was to be able to solve issues like latency and resource optimization on a completely different level and create a lively playground/environment for both software developers and hardware engineers to work on.
Basically, we're currently actively working hard towards proving the claims and fulfilling promises that we're currently making!
App development wouldn't necessarily be the only functionality of AI in the OS but it will definitely be a primary one.

Is this building on that or a complete bottoms up writing of the full AR software stack?
What open standards does it support? OpenXR, WebGPU, WebXR?
What industries are best suited? Games/Entertainment/ Sports? AEC?
It currently doesn't support any open standard but we're targeting OpenXR standard and also some native way of application writing where developer doesn't need to care about whether they are writing for XR devices or other devices. The OS will take care of it.
Currently we are more focused on building a lifestyle product experience, which includes Games, Entertainment and general daily use cases like navigation, etc.
