I think we talk here about a business model. While PSTN stands more for technology, Telco world will be with us, no matter they use TDM, ISDN, SIP or SIPng...

Similar to NAT, which would do security even IP address shortage would be a past, PSTN-model is a walled-garden communication environment, protecting from "buhoohalaa" threats of wide Internet.
