Serendipitously, 5 years is roughly the maximum life span of a queen
bee.  However, it is a pretty safe bet that if they are emulating a bee
brain, it is a worker bee brain, and a worker bee is lucky if it lives a
couple of months.  

Did it say anywhere that the emulation was real time?  Very common for
emulations to run orders of magnitude slower than real time, so
processor loss could still be an issue during runs.
