Oh, I hope not. Sometimes information is carried by the layout. For 
example, if I write a class:

class Spam:

    def foo(self): ...
    def bar(self): ...
    def baz(self): ...

    def foobar(self): ...


then without me saying anything, the reader should realise that foo, bar 
and baz, but not foobar, go together in a weak sense. If it were a strong 
sense, foobar ought to go into a separate class.

A real example: writing getters and setters for property. Particularly if 
they are one or two line methods, I'll usually run them together with no 
separating blank lines to emphasize that they belong together.

ASTs often don't include comments, so that's a problem.

Yes. In my opinion, mobile computing is a huge step backwards for 
personal control of your own hardware, usability, and power. In my 
opinion, people will look back at the first decade of the 21st century as 
the golden age of personal computing.
