I feel like the people I interact with irl don’t even know how to boot from a USB. People here probably know how to do some form of coding or at least navigate a directory through the command line. Stg I would bet money on the average person not even being able to create a Lemmy account without assistance.
Intelligence isnt a linear scale. There are so many skills out there, so many things to learn. You might consider tech people more intelligent because the skills they have are the ones you recognise as intelligent.
