Genes propagate information through replication, a key process in life and evolution. When information transfers from one genetic substances to another, say RNA to DNA, we call that takeover.
Memes are especially susceptible to takeover. Oral tradition to literature to talk radio, for example.
Some fear that humans are engineering their own takeover by artificially intelligent machines. I'm less fearful because the computer hardware supply chain is so long and fragile. We're much more likely to loose the ability to sustain the machines before they replace us.
We're much more likely to unleash persistent pests upon ourselves with GMOs or more exotic replicators.
