You can't invent your own physics. You're forgetting that we can't make batteries denser any longer and these things need batteries...and sensors...and camera..and wifi...and bluetooth...and the charging port. If you try to fit all this into a regular glasses form factor with a modern graphical operating system you'll probably have about 5 minutes of battery life.
There's a limit to how small these things can be miniaturised anyway. Below that and they become fragile and hot.
In a world where Apple has made a MacBookPro capable of desktop level performance that can run for 20 hours when 10 hours had been the max limit for so long, it was considered a max ceiling for laptops, how is this even an argument?
Apple silicon changed the game. What was once impossible became the norm. When it comes to miniaturization capable of fitting performance + battery efficiency into a tiny wearable package, look no further than the Apple Watch that in generation after generation defied the max limits of what kind of computer could fit on a wrist.
We're not even remotely close to hitting the limits of physics. You don't need bigger batteries, you need more efficiency and Apple has proven that repeatedly with the Apple Watch and AirPods, both of which improved on their performance while lasting longer, and without needing to grow their battery size.
For context, you could fit today's Apple Watch components, including its battery, distributed into the length of a single stem of a pair of Ray-Ban style glasses. Two stems, and you're doubling the entire Watch performance and battery capacity, without even accounting for year-over-year performance improvements and ignoring the front frame of the glasses which would theoretically be left for the projection/displays and nothing else to be as lightweight as possible. It's likely that the glasses will be running one or more M3 level chips, instead of Apple Watch silicon, which it's going to need for performance and efficiency to run AR applications and two displays – if not retinal projectors.
This is just the baseline of what we know of today's technology. It's possible with what Apple already has on the market today, let alone with the technology that they haven't unveiled yet, built specifically for this new device category.
