It's not such a good bet.  In fact, phonon pumping makes it easy to
explain a catastrophic change in mental evolutionary history.  The
pump rate is a critical parameter, which when below a certain point
the condensate will not form.  The phonon count is a soft parameter.
The theory only has a phase transitionin the statistical mechanical
limit as the number goes to infinity.  At low enough counts, there
will again be no condensation.
