Right from Glass’s highlights website:
We’re wrapping up the final touches on our AI-powered Search beta that we’ll be releasing soon to Early Access. Early Access is an included perk for a new level of Glass membership that we’re announcing soon. Once we’ve tested it thoroughly over the coming months, it’ll be released to everyone.

In other words, Glass will add another subscription level where you’ll get pre-release features for testing. Subscriptions are not enough. Now we must pay to be beta testers. Great. 🤦🏻♂️
