Say you have a 1 GB file that you want to share with everybody in this thread. How do you do this? What if you have thousands of such files? In theory, DAT and similar DHT-based file sharing protocols, can enable us to implement something like YouTube, but without the enormous costs for running the datacenters. In practice, ISPs won't let this happen and DAT-like protocols will be limited to the world of VPSes that have static IP addresses.

Greed. Humanity has always been driven by greed, but the hope was that it would recognize and overcome this sin and get to the next level. This hasn't happened. I have a weird feeling that humanity (or rather this civilization that started about 10k years b.c.) has just missed the critical point when it needed to take off. The greed was too heavy and we've started losing altitude. In practice, losing altitude manifests as the raising temperatures: the only way to solve this problem is to overcome greed.
