SFAIK, a &quot;patch&quot; to the icing problem has been deployed. I suspect it&#x27;ll be like that - undiagnosed defects emerge, get patched, repeat, lather, rinse. Somebody once called this &quot;like simluated annealing&quot; to me ( I lack the materials chops to say if that&#x27;s true or not ).<p>The problem with this is that it&#x27;s very hard to communicate the realities of this to &quot;end users&quot;. They may have Luddite streaks to start with and may be looking for an excuse to ... defect from the relationship with the machines for very real reasons that have nothing to do with the actual operational virtues of the machines.<p>You can&#x27;t really tell them that they are wrong, either. 
The fact that you and I both know the icing story is evidence that this is unusual.
