Author is a doofus, but there is one context in which I sorta agree with this sentiment.
It drives me up the wall when, according to my browser, a page is done loading, so I go to click on something and bam, a subscription/cookie/whatever popup appears and steals my click in the millisecond between when I decided to click and when my finger reacted.
Everyone else is gonna be like "if you don't have at least 3 backups of something blahblah" but you know, not everyone has the finances for that, so advice from a cheapskate computer nerd: when going through critical transfers/reformats/deletions like you were doing, ALWAYS try actually recovering stuff from the backup before you cross the point of no return. E.g. if the backup is a .zip, extract a few individual files from it and open them in their respective programs.
