Remember the great Y2K computer scare? A lot of us who were using PCs for work & business had to buy new hardware & software to ensure we could keep operating, just because some bozos couldn't concieve of the date changing. That's nothing compared to the goat-f**k that's going to happen when the government runs out of social security numbers. Current 9 digit SSN structure allows 999,999,999 numbers, but only up to 765-XX-XXXX have been allocated. The US population in 1934 was about 120,000,000. Now it's close to 300,000,000 and increasing about 2,500,000 a year. Assuming normal population growth, I guestimate we'll run out of 9 digit numbers in 70-80 years.
