People talk about software ossification as being bad, but is it always?
One thing I like about ossification is that you can take the analogy in very interesting directions if you compare the strength of a structure (or software system) by thinking of it in terms of rigid vs flexible rather than strong vs weak.
Rigid structures don't survive earthquakes or other major changes, however all building structures need rigidity or they won't be able to last at all and will collapse.
