SSNs don't even have a checksum to detect typos, nor any convenient mechanism to issue a replacement number if one is compromised.
Using the security flaws of the SSN implementation to justify security flaws in any modern identity system is just not rational. If anything it shows that people didn't learn from history.
> Social Security Number in the US pre-dates the internet and any concerns people had about privacy.
People in the US were concerned about privacy long before the Internet. The 4th Amendment to the US Constitution dates back to the 18th century, for example.
In fact, I'd say people are much less concerned about privacy in the Internet era; they put everything online and happily give private info to corporations and government.
Or literally get a birth certificate and become a "US citizen".
It's a bit more complicated, but not impossible, to do that in the UK, Belgium and Germany as well. Probably other countries, too.
So you're all crying about India being dystopian while your own ID systems are completely fucked.
IMO the IRS should not be using SSN's for identification. But i'm not sure what else they can use.
