Well I used to think 32 bit integers were good enough for everyone, but 
now I wish that all our integers went on to infinity, as some clever 
person probably wants to create some program you never dreamed of that 
will hit the integer limit...

But for dumb things like web stores, blogs... Yes.

For some physics simulation that is a massive number cruncher "no 
integer is ever big enough"...
