meme fitness

Meme 'fitness' is not dependent on the meme itself having any properties of good 'quality'.

It just needs an environment that increases replicability.

Case in point is the 'Amazon didn't kill the retail industry...' thing that has replicated itself successfully despite being complete horseshit.

None of those 'dead' things are dead.
Apart from Blockbuster, which was a brand rather than a category in any case.

But the meme is selected for in a Dunning-Kruger environment.
