Here is an important difference. A century ago, the predator (seller) and the prey (buyer) were on equal evolutionary terms. Each generation of humans on either side of the transaction came into the world, learned to convince, learned to resist, then passed, and some balance was maintained. In this century, corporations and algorithms don't die, but the targets do. This means that the non-human seller is continuously, even immortally, learning, adapting and perfecting how to manipulate. The target, be it adult, adolescent, or child, is, and will be ever increasingly, at a severe disadvantage.
