    Forgive the top posting:

    Apoptosis is the genetically controlled death of cells based on the
    signals they receive from their neighbours. It is a form of cellular
    altruism that makes sense only at the level of organism selection -
    those organisms that have a failure of apoptotic mechanisms in some of
    their cells end up with cancer or developmental malformations or
    diseases like elephantisis.

    Memes could only be "programmed" to extinguish themselves if they were
    carried as part of a developmental program for a larger memeplex. And
    instance might be the teaching of billiard ball physics to students
    before they learn about the joys of QM and relativity theory.

    A better instance might be the "idea gas law" - teach them that first,
    then start teaching them about its failures, under P's that make van der
    Waals forces significant, etc. In this respect those propaedeutic memes
    might be seen as scaffolding for later more adaptive memes in the
    context of more sophisticated "ecologies" (ie, technologies).
