What makes you so confident that is the case? I listen to lots of classical music and certainly hear musicians breathing, even on older recordings. I would imagine fingernails on a keyboard are of a similar decibel level.
I saw a Dr the other week (to rule out Covid and strep) and despite testing negative for both and telling me I just had a cold she offered me antibiotics. I declined, not wanting to be part of this problem, but was taken aback that she would basically try to push them on me.
I used to work as a librarian and ran into the issues the author writes about. Less than she did - but it being a community that skewed older I have plenty of experience shepparding older and/or low income individuals through basic online tasks such as applying for unemployment etc. If you have never done this kind of work then it is very easy to take for granted how low the baseline technology competency of certain folks is. Telling someone they will need a working phone number, a password, and recovery codes to access their email when "it used to just work" will simply not fly for them.
This side steps the issue that often these are scenarios where the patron is already locked out of their account and coming into a library as a last resort - so lecturing them on backup codes will be of no avail.
