Ah, I might be unduly affected by some big data (not Big Data, mind you) migrations that I'm currently involved in, where the Powers That Be are telling us that we have to throw away a huge fraction of our historical data. Well, that and the many times we've had to fight beancounters who popped on by to demand we save the company what amounts to pocket change by throwing away tons of historical data.
(It's flabbergasting how beancounters tend to ignore the price of programmer time when making their cost-cutting spreadsheets.)
I imagine the beancounters have little hope of just making the programmers go away, so they might as well be doing something useful :)
