Those who don't learn from history are doomed to repeat it.

People can mismange anything into oblivion. IPv6 will end up the same mess IPv4 has become. (granted, it should take more than 30 years this time.)
To burn through all the /48s in 100 years, we'll have to use them up at the rate of 89,255 *per second*. That implies either *really* good aggregation, or your routers having enough CPU to handle the BGP churn caused by 90K new prefixes arriving on the Internet per second. Oh, and hot-pluggable memory, you'll need another terabyte of RAM every few hours. At that point, running out of prefixes is the *least* of your worries.
