How many years until General Direct Dialed telephony dies?

Discuss.

As I'd posted this poll a week or so back, general direct-dialed telephony, a/k/a PSTN (public switched telephone networks) seem to be in trouble. I think we could be within five years of their total collapse. And no, not just land lines (already about 25% of their peak in much of the US), but _all_ direct-dialed phones: mobile and VOIP included.

The problem, as I'd written before, is paradoxically the _low_ cost of calls. This is inducing tremendous volumes of junk calls, with one ...

@dredmorbius It's the #@*&#@$ topology - any can reach any in one step is a nightmare. An absolute nightmare. That's what's going to take us down. We need something like web of trust to put a distance metric back in; anything that doesn't have one is going to implode.

@kensanata Whitelisting, with a possible distribution of (preferably locally/limited) vetted general numbers, would be preferred. Blacklisting does not scale, present systems prove this.

Vetted numbers would include local or regional service and government contacts, though those would then become attack / spoof targets for spammers. A well-known vetted number can reach many others. 1:1 whitelist personal contacts, not so much.
