Being careful is not enough, you also have to be competent. You can be careful all you want, I had to expain to an HNer earlier for example how .js files on windows are actually native executable scripts. Is a lay person supposed to know that for example?
Depends, some containers like vhd and iso don'get the warning or archive formats not supported by windows like rar or 7z either. And that warning is very ineffective.

This isn't the 60s. Computere are made and marketed for regular lay persons/general public.
hmmm so when you do projects with people and someone you haven't heard from in a while shows up and wants to show you what they are working on your first thought should be to grill them in the third degree and ask them the color of their underwear to make sure it's them...
He's not wrong.
