I don’t agree. Even in languages where tabs are syntactically equivalent to spaces tabs mean something else to the programmers.
In my shop we use tabs only for indenting. Which means I can set it to a comfortable 2 spaces when working on my laptop (small screen) and 8 spaces when working on my desktop (humongous screen) because it makes seeing the indentation easier.
I never understood the advantage of using spaces for indenting. Except maybe that lots of text editors are retarded and insist on inserting spaces all the time.
My guess is that it’s age related. Older coders learned the trade using plain old text editors (where using tabs is a bigger advantage), the younger generation probably always used IDEs where using TABS still is an advantage (IMHO) but less so.
