alt Hacker NewsIt sounds plausible, but only in the shallowest “yeah, make ‘em look the same” way. Just like when they started shipping the Catalyst-based Mac apps of Messages, Photos, etc so that they’d look the same as the iOS apps (and no doubt so they could reuse some code from there instead of wasting developers on the Mac platform they hate).
It’s not as though anything about Liquid Glass makes a meaningful difference in usability.
I think this goes deeper. Transparency is clearly not a good fit for desktop or mobile apps, but imagine smart glasses where every app completely blocks your view of the things behind it. It just wouldn't work.
To move around safely with smart glasses on your face, apps need to be semi transparent from day one. It's not about superficial stylistic similarities this time. And it's not primarily about design either.
This is absolutely about core usability, just not for macOS or iOS.
