This story isn't about software, either. The title is the only computer science reference in the whole thing. It reaches no conclusion. It likely does not even make any points that you haven't thought of yourself at some point, though if I'm lucky it hasn't been presented to you before in quite this way. It might even be offensive.
Consider two groups of people. The demographics between these groups are similar in every externally observable way: all ranges of age, all genders, all manners of ethnicity, some with good fashion sense and some without, some tall and some short, some bald and some quite hairy. If a member of one of these groups stood in front of you, you would not be able to classify them into either group even after detailed study, but after five minutes of casual conversation it should become clear to which group they belong.
