A quick biology lesson Cells contain genes. Genes provide the code to replicate those cells. Cells replicate so the bodies they inhabit can live long enough to reproduce and pass those genes to the next generation. Sometimes this process goes wonky, and genetic mutations cause cells to begin replicating out of control. We call these cells cancerous. DNA strands have little strings of code on the ends called telomeres. Every time a cell divides, one unit of the telomere gets used up. Once the telomere is gone, the cell can no longer divide. Cancerous cells eventually stop replicating because the telomere gets used up. Telomeres, thus, protect against cancer.
Every side claims to know the truth of memes (the opposition and their "prions" too), but there are nuance to it. There are ways that memes fight each other. We can only hope for territory theory to be correct (conditioning and inoculation) https://generativist.substack.com/p/bullshit-is-prionic/comment/5301102?s=r
“Every day I think about untwisting and untangling these strings I'm in, and to lead a pure life. I look ahead at a clear sky. Ain't gonna get there but it's a nice dream, it's a nice dream.”
