my neighbour took a low end programming certificate from a college with open book tests. i used to work in IT with email servers and security stuff. i can't have a conversation with the neighbour about anything current in IT (i keep up to date by reading tech articles, etc. with little to no effort. Eg. i read the Bitcoin whitepaper) because the neighbour has no clue about anything in the IT world yet has a job in it. It's mind boggling.
