But the internet has one very important job: Allow us to prevent global climate catastrophe. It would be impossible without the internet. Only by integrating all of our cultures together into one giant knot, and having armies of people coordinating together in loose federation can we implement the myriad social, architectural, and cultural changes that we need to do in order to prevent a major environmental calamity from becoming an ecosystem-leveling tragedy.

That sounds very grandiose, and perhaps I'm out of touch, but I'm not really pumping it up for rhetorical effect. That's a pretty flat representation of what I actually believe we are facing.
