No, neither of the first two were ever theoretically impossible, even if
people believed they couldn't be done (right, so a bullet/rocket can fly faster 
than sound but a 'plane cannot?)

>Why is it .. I just don't believe you?

I'm stressing "brute force" for a reason; it cannot be brute forced.

Now, if someone cracks AES then that is an entirely different method
(and that would mean using something other than brute force).  Doubling 
the key size may or mey not help in that case.

Right, but I'm not sure it was possible then, though such systems were 
clearly build later on.

It seems that the NSA has given up on stronger crypto algorithms but is 
now focusing on making people generate poor key material instead.

Other methods != brute force.
