A couple of observations on Y2K accommodation.
-- As my shop was slogging through remediation required for year 2000,
insurance companies apparently coasted along because they had ALWAYS needed to
handle four-digit years from the inception of IT. For them it was business as
usual.
-- Can't cite attribution, but I remember the calculation that despite our late
1990s poignant misery, the ancient choice to represent dates with two digits
was actually economically correct. The burdensome cost of both media and memory
storage in, say, 1970, outweighed on balance the eventual cost of remediation.
It's easy to ask what difference two bytes would have made, but the hard-money
cost of billions and billions of 'extra' bytes would have been substantial.
the smart solution would have been to store year as 2 bytes binary
integer, they'd have been good for 65535 years...
