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.
