I don’t find “good chunk” compelling. I think you need to do a more rigorous analysis of the costs and benefits. FCC is fully capable of creating the incentive structure to maintain a spam-free PSTN. This is a political problem.

IP addresses and phone numbers are indistinguishable in the context of spam. If you successfully argue that the PSTN cannot be operated at a net benefit to society because of spam volume the same argument must also be a valid call to shut down the Internet.

I only said “good chunk” because there are already more than a few reports pointing to a shift in behavioral patterns around calls. (Feel free to Google, Bing, or DuckDuckGo it when you have a chance.) The point is less about an exact percentage and more about the fact that user behavior has already adapted in ways that erode PSTN’s practical value.

And if the FCC were fully capable of solving this problem, I don’t think we’d still be here after decades of the same issues. That longevity itself is part of my argument: it’s not that people haven’t tried, it’s that the structural limitations resist a clean fix.

Also, IP addresses aren’t a great analogy. They’re not a sole indicator of origination — we have layers of metadata, routing, and reputation systems around them. I’d accept that comparison more readily if phone numbers were spoof-proof. But they aren’t, and that’s yet another area where the FCC hasn’t managed to close the gap.

Yes, such reports exist and they are easy to find when you look for them. My point is that you are not balancing these reports with the benefits of the PSTN or considering that people who happily use the PSTN aren't vocal about it. I think you are attributing way too much weight to the information you can find, especially when you are looking for it. You then draw an extreme conclusion that the PSTN is not worth maintaining and support it with this flawed analysis of behavioral change.

You might be right but the way you have substantiated your argument isn't compelling.

I’m not claiming universal truth. I’m stating that under the evaluative lens I’ve made explicit, PSTN doesn’t meet the threshold for viability. That’s the scope of my argument, and it stands on its own terms.

You’re welcome to use a different standard, but dismissing mine as "not compelling" without engaging the actual framing isn’t critique. It’s rhetorical displacement. If you’re not addressing the criteria I laid out, you’re not engaging the argument.

Speculation cuts both ways. If you want to challenge the standard itself, do so directly. Otherwise, implying imbalance or extremity without entering the terrain is performative, not substantive.
