I do not think any “special education” is needed to explain people how 
to scroll horizontally...

No, but I tried to present arguments. Do you have evidence?

Not very, I think.

Also, line breaks still have significance in some languages, this 
wouldn’t solve that.

Pretty much every one of them? Eclipse, IntelliJ, Visual Studio, 
MonoDevelop, Netbeans, XCode, you name it... Even my old colleague who 
used to use Vim for sure didn’t have it set to line wrap.

I mean it makes sense for plain text documents, and I guess the editors 
you named are intended as generic text editors, but not for source code. 
If you’d be editing source code in them you’d be turning off the wrap 
option in a jiffy.

Also, fwiw, Github doesn’t wrap either, nor does Stack Overflow, nor 
does the Android documentation. Nor will anything else on the web that 
shows source code. I dare you to find a place ;P.
