> I can see a future where I’m cut off from parts of the web because of captchas.
I’ve seen this in past and present. Google’s “click on all the bicycles” one is notoriously hard, and I’ve had situations where I just gave up after a few dozen screens.
Chinese captchas are the worst on this sense, but they’re unusual and clearly pick up details which are invisible to me. I’ve sometimes failed the same captcha a dozen times and then saw a Chinese person complete the next one successfully on a single attempt, on the same browser session. I don’t now if they measure mouse movement speed, precision, or what, but it’s clearly something that varies per person.
