I agree, that they are missing a big opportunity not supporting all 200 Vision Pro users with built in eye tracking.

Especially as they are moving into showing ads.

https://www.apple.com/apple-vision-pro/ under Privacy and Security: "Eye input is not shared with Apple, third-party apps, or websites. Only your final selections are transmitted when you tap your fingers together."

We'll see. I remember when the iPhone wasn't going to support native code apps in favor of web apps for privacy and security reasons.

That turned out differently.

Where and when did you find that?

In the Jurassic age. More info if you are curious:

That was great I'd like more info. I'm not sure how Jobs figured web apps would've been practical given a lot of things were still using flash at the time.

We didn't have frameworks like React back then, as far as I know there was pretty much JQuery.

But considering how a lot of projects are moving to web technology these days, it sort of showed how forward thinking he was...

Every heart palpation will be analyzed and monetized!

You jest, but I know of a company that does just that very thing using smartwatches in marketing research.
