The law of ad entropy in technology states that over time, ad coverage always increases. First in the applications hosted on the platform, and then eventually the platform itself will just start serving ads. At the heat death of technology, all platforms will be completely covered in ads, leaving no more more energy for useful work.
See: the web itself, search engines, app stores, desktop search, operating systems from desktop to mobile to TV... the list is endless and the trend is relentless. It already started with AI, now injecting ads directly into chats.
So I think it's not a stretch to predict AR platforms will be the same and the ads will be in your eyeballs. It doesn't really matter that these anti-features will cause the product to be worse for users if it makes the platform more profitable for owners.
I can also guarantee with complete certainty that any sort of "neural implant" technology will one day be serving ads directly into your brain.
