I wouldn’t say that it’d be strictly impossible, however if it can be done then it would come at a considerable cost to useability, versatility, etc.
One adjacent concept that comes to mind is the use of the :visited CSS tag to extract a user’s browsing habits. I remember seeing a demonstration of this where an “are you human” captcha was shown but the choice of image in each box was controlled by the :visited tag. I can’t find that post, but this medium article demonstrates a similer concept. There are mitigations to this luckily, but a fullproof solution would be to remove the tag’s functionality altogether, which would make certain websites (like the one we’re on right now!) much more inconvenient to use.
It seems trivial to me for a website to detect user behaviors that indicate the use of an adblocker. For example, if a request for a page is immediately followed by a request for a video on that page, rather than after 5-60 seconds, then they’re likey using an adblocker. If there is an ad placed between two paragaphs in an article, but two distant paragraphs are visible at the same time, it is more likely (although not guaranteed) that they are using an adblocker. If a user triggers an abnormal amount of those heuristics then they get flagged as an adblocking user.
While I do agree that math gets much easier with interest, and that it gets more interesting the further you get into it, and that math is inherently beautiful, etc. I feel this argument has to fall flat to people who don’t already agree. It’s the education equivalent of when someone says they couldn’t get into an anime and then the fans tell them ‘oh it gets really good around season 9’. You could be completely correct, as you are here, but it’s utterly unconvincing if you don’t already “know.”
To be fair, I think this is mostly a problem with math curricula. Math classes up through high school and early college seem to focus on well trodden solutions to boring problems, and at some (far too late) point it flips around to being creative solutions to interesting problems. I think this could be fixed eventually, but such is the system we have now.
