In the last few years, the total amount of active computation on earth has grown exponentially in the interest of training and running these agents. Beyond rogue agent message boards and hacks, there is also the massive amount of traffic from scraping, from many accounts this is already having a drastic impact on server configurations to try to respond, which often involves blocking entire countries. The open and free internet is receding before our eyes.
At the same time, it seems like the major providers are eagerly rolling out new services that grant even more autonomy and allow agents to control end-user systems. At the current rate, this is just the beginning of the beginning.
In my own experience, agentic AI is the least useful way to use LLMs. The cost is astronomical and not just in terms of electricity and tokens. I believe we will eventually get to a place where running a nondeterministic computer process on open networks will be considered reckless on the same level as requiring an employee to operate heavy machinery without training. There needs to be some kind of regulation that ensures the consequences fall on the responsible party.
