Asked by a student for an example of infectious cultural junk that is hard to eradicate, I replied, "Well, it's like, when, like, you use a phrase which, like, isn't really, like, doing any serious work, but, like you go on, like, using it." To which the student replied, "I, like, understand the point, but I wanted, like, an example.

We Homo sapiens are the only species (so far) with richly cumulative culture, and the key ingredient of culture that makes this possible is language.

Perhaps we are just apes with brains being manipulated by memes in much the way we are manipulated by the cold virus. Instead of looking only at the prerequisite competences our ancestors needed to have in order for language to get under way, perhaps we should also consider unusual vulnerabilities that might make our ancestors the ideal hosts for infectious but nonvirulent habits (memes) that allowed us to live and stay mobile long enough for them to replicate through our populations.

The claim that I defend is that human culture started out profoundly Darwinian, with uncomprehending competences yielding various valuable structures in roughly the way termites build their castles, and then gradually de-Darwinized, becoming ever more efficient in its ways of searching Design Space. In short, as human culture evolved, it fed on the fruits of its own evolution, increasing its design powers by utilizing information in ever more powerful ways.

The Absolute Ignorance of evolution by natural selection is indeed capable of creating not just daisies and fish but also human beings who in turn have the competence to build cities and theories and poems and airplanes, and computers, which in turn could in principle achieve Artificial Intelligence with even higher levels of creative skill than their human creators.

Quantity isnt to be equated with quality, but success in propagation is, in the end, as necessary for memes (however excellent) as it is for organisms. Most organisms leave no issue, and most published books have readerships in the dozens, not thousands, before going out of print for good. Even the greatest works of genius must still pass the test of differential replication.
