Is a detection-proof ad blocker theoretically possible?
Not asking for tech support here, just wondering if in theory it would be possible to create a plug-in or even a complete browser that blocks ads in a way that's impossible to detect. One model that comes to mind is a quarantined / containerized non-blocking virtual browser which queries the web server directly, then the UX filters the content from that container and presents it to the user ad-free. As far as the web server can tell, the containerized browser is just vanilla Chromium.
Theoretically, an air-gapped system that is worn on the head, rather than installed to the device would be undetectable.
An AR vision headset that detected known-ad-signatures and could blank or replace ads in realtime, with targetted noise-cancelling to 'mute' specific ad audio, could surgically remove ads from any media(billboard, magazine, video, radio, webpage).
The major problem with ads isn't that they are a visual and audible nightmare (although that IS a problem), it's that they can affect performance and are vectors for malware.
Alternatively, a program that is a wrapper for your entire browser/device, that observes video and audio, to automatically carry out the blanking/muting.
Ads load as normally, but are never seen or heard by the user.
