I like this analogy. Silicon valley generates random mutations of existing ideas, without thought or direction, and occasionally lands, by pure chance, on something slightly better, which survives at the expense of other inferior mutations.

I guess that maybe the developers working on "a new way to share photos and video" kid themselves that they're making something different; something that really is revolutionary. But no, what they're really doing is tweaking the shape of a beak thinking it'll make a better finch.

So I do kind of have to ask: is making random tweaks to the genome of the photo sharing application in the hope they'll be successful really the best use of the talents of all those developers?
