 From the second source:

"If all these unused ASNs could be recovered, the pool of ASNs would 
last until 2025 to 2030."

So, if we think that 2^32 is ultimately unobtainable, we're just facing 
a deadline with 2^32's being the "norm" per AS of a few years longer. Of 
course, this doesn't even answer the question of how to get from 2^18 
currently, to 2^32 in the first place.
