There are benefits to keeping code less far to the right on the line for easy reading. I review a fair bit of code these days, and I’ve never once wished someone used more characters for their variable names. Long variable names have a tendency to make the code they are part of wrap a lot and become hard to read.
I think a lot of people think that a verbose variable name is always better, so they end up lazy and don’t try to figure out what makes the variable interesting in context.
