This.

I’m not talking about science, who knows what those wizards are doing, unless you’re talking about computer science which I am.

the problem is when you abbreviate something or use three letters or a number to represent something it gets forgotten over time, the protocol changes but more importantly it is impossible to remember what all those 3 symbol representations actually mean.

In the old days we had a good reason for this, literally only so many letters could fit on a line, but now if you’re doing it you’re just a dick.
