You argued it’s “the most useless idea ever committed to text”, that’s a bad take. No one claimed that it’s a rigorous scientific theory, that’s your failure to understand the premise. It’s a useful analogy, like the useful observation that electricity in a circuit behaves in many ways like water in a pipe, or that Einsteinian spacetime behaves in many ways like a rubber sheet. Are these analogies “useless” because electricity isn’t in fact water, and space-time is not in fact rubber? Or would a self-righteous PhD make themselves look supremely foolish by attacking these illustrative analogies as useless because they aren’t rigorous scientific theories?

Having read most of your sources here, they do not support your conclusion. I see opinion pieces, confessions of the authors’ personal inabilities to imagine the granularity of a singular meme, lamentations over different authors’ conflicting definition of a meme, and smug conflation of memetic behavior and the substance of consciousness, but not claims that the idea is useless. Non rigorous, over extended, inconsistently defined, sure. But useless? Much less the most useless idea ever committed to text? That is your own myopic hyperbole.
