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.
