Sure I2 contributes. But something else would take it's place.
I was wasting my time over at a gaming site, before I started
looking into Asperger's. Then I switched to WP, and spent
too much time there.
As to the philosophy, it is merely an absurdity. Not worth
defending or preaching. It is really based upon the pun,
"Nothing is better than the best thing." It's not a categorical
error, and I can't really see the flaw in it. Not much to do
with life sucking, actually.
Comes down to, if there is no point to it all, it just doesn't
make a bit of difference, and nothingness is an aesthetically
more pleasing way to have no point. What if there is some
point? Well, without knowing it, one can't be certain of
acting towards it (or if it is good or not), so you're almost
in the same position as there being no point, but less
empowered - a circumstance which seems much less
attractive than absolute non-existence.
