you are right - it doesn’t have to be one or the other… I just assume that for social media to work as I expect I don’t know most of the people on the platform. given that assumption and the lowering price of creating bots and ability to onboard them I expect that eventually most of the actors on the platform will end up being bots. people that write them are often insanely motivated (politically or financially) and creating barriers for them is not easy.
