100% this. To understand code written with Greek letters you'd also need to understand the author's intentions for using said letters. Is mu an average or coeff of friction? Why should I lean on a crutch of context for a casual skim of code? It doesn't help readability and it surely isn't enjoyable to write.

It all depends on context. Short identifiers absolutely help readability. I feel like some people absolutely go too far with overly verbose variable names, especially in Java or C#.

Notation matters. What if I told you that to add two numbers you had to write it out as plus(number, number)? Clearly you'd riot. The reason people complain about short IDs is because they're not used to it, but there are a lot of domains (math, science) where using traditional notation enhances understanding. Hell, even in programming if someone wrote sequenceIndex instead of i when iterating over the indices of an array I'd think they were trying to troll.

Aditionaly, in statistics Greek letters denote parameters, while the modern Latin alphabet we all use today is for variables. The data `x` has a normal(mu, Sigma) distribution, for example.

These sorts of conventions enhance readability by providing extra information. You know instantly that `y` must be data, while `theta` is a parameter.

I thought Racket (starting with BSL) to incoming freshman at Northeastern University, and they would nearly riot every year when we tell them it's `(+ 1 1)` for the next 4 months (at least).

If it's hard to write then you can just improve your editor; there are lots of ways to do that, and most of them involve improving the software rather than hardware. Having a lousy editor is no excuse!
