When I was a residential garbage collector, I saved close to a dozen computers from the landfill that just needed a quick cleaning. A lot of people will get rid of their year old Alienware once it fills with cat hair.

Doesn't mean it won't either - most people won't realise the computer is still usable, either by workarounds or installing a different OS - they'll either trash the PC, recycle or sell it. Or keep using it not caring that its complaining constantly that it's out of support. (And when they do, it's "how can I get rid of this annoying error" not "how can I update this?" - they probably didn't even read the error - and god forbid you manage to do the update, they won't like it if you do)

Hell most people don't even know Linux even exists, and a lot of them couldn't even tell me what their operating system name is.

I've had relatives that try to ask what's going on and say "I have 11" without elaborating that it's windows 11. I remember years ago my aunt said I have version 97. Referring to, at the time the totally unrelated fact that she had Office 97 installed on her winXP machine. Took me ages to work out what she actually meant.

80% will.
