C.G.P. Grey explains memetics

C.G.P. Grey explains memetics in terms of "thought germs" in the following excellent video titled "This Video Will Make You Angry":

Notable previous videos from C.G.P. Grey include:

• Humans Need Not Apply (Automation)
• This Video Will Hurt (Nocebos)

I suspect that the content of "This Video Will Make You Angry" was inspired by Scott Alexander's essay The toxoplasma of rage - which came out a few months earlier and covers much the same topic.
