In what system are those bots going to be hosted on? It'd be hard to avoid centralization on a premise that bots would play a major role in the market.
These bots can hop from provider to provider as needed, such as a host or on a network like Ethereum is building. They can do anything you can on the tech level.
Bots don't change much, they ultimately are still owned and controlled by a human.
Universal income will come from bots. (the minimum rights/power every human is believed to be entitled to)
