If only 90% can solve the captcha within one minute, it does not follow that the other 10% are completely unable to solve it and faced with “yet another barrier to living in our modern society”.
It could be that the other 10% just need a longer time period to solve it (which might still be relatively trivial, like needing 2 or 3 minutes) or they may need multiple tries.
If we are talking about someone at the extreme low end of the captcha proficiency distribution, such that the person can not even solve in a half hour something that 90% of the population can answer in 60 seconds, then I would expect that person to already need assistance with setting up an email account/completing government forms online/etc, so whoever is helping them with that would also help with the captcha.
(I am also assuming that this post is only for vision-based captchas, and blind people would still take a hearing-based alternative.)
