I had the same reaction! “legacy baggage” is a vague phrase. Without examples (like specific subsystems or bottlenecks), it’s hard to see how a custom kernel helps XR more than existing lightweight or RT kernels. If the team has benchmarks or case studies where Linux/Android gets in the way, that would make the argument much stronger.

We get what you're saying. The claims that we're making do indeed seem like just claims for now but we're actively working on real life benchmarks in comparison to industry standards.

Stay tuned for our Public Beta/Prototype showcase scheduled later this year!
