The Internet Will End in 30 Years!

Have you heard the latest doomsday scenario?
In thirty years, the internet will stop working! Apparently, a bug
similar to the millennium bug will affect Unix-based systems, like
those that run the tubes, in the year 2038. The bug, being dubbed the
"2038 bug," arises because Unix-based systems store the time as a
signed 32-bit integer, in seconds, from midnight on January 1 1970. And
the latest time that can be represented in that format, by the Posix
standard, is 3:14 AM on January 19, 2038. After that, times will wrap
around and be represented as a negative number.




And then what happens?



Programs will fail, of course. Since they will see times not as
being in 2038 but rather in 1901, erroneous calculations and decisions
will occur. (It's true, I checked Wikipedia!)

We've actually seen fallout from the 2038 bug already, back in May
of 2006 when the AOLserver web server software crashed. The software
was designed so that database requests would "never" time out. Instead
of assigning a "0" to the timeout, the software specified a timeout
date one billion seconds in the future. One billion seconds (just over
31 years 251 days and 12 hours) after 21:27:28 on 12 May 2006 is beyond
the 2038 cutoff date. The system calculated a timeout date that was
actually in the past, got confused, and crashed.

By 2038, it's likely that many of the susceptible machines will have
been decommissioned before the critical date occurs. However, legacy
systems and embedded systems could still be affected. These may include
process control computers, space probe computers, embedded systems in
traffic light controllers, navigation systems, routers, gas pumps, etc.
It may not be possible to upgrade many of these systems, so they will
need to be replaced.

And as for the internet?

Well, I'm pretty sure that self-improving Artificial Intelligences will be running the world by then, so we probably don't need to worry too much about this.
