I used to teach computer science first semesters a few years ago and I got tons of emails from people who couldn't manage to boot and/or install the linux distro we gave them on an introductory usb drive. These were intelligent kids with plenty of education and many of them couldn't figure out how to do basic networking or formatting stuff either.

My working class dad who had like 8 years of formal education in his entire life taught himself visual basic in the 90s through magazines and books. Getting emails from students who could theoretically just type stuff into google at 1 am was a genuine shocker to me.

(this is Germany in my case)
