We have already passed the critical point. The LLMs, the agent harnesses are here. There is too much willpower, capital, and risk behind these technologies now—the automobile has landed, thousands of people have purchased it already, protesting the car won't undo it at this point.
What you can do that will be meaningful, is to instead understand the new car, and understand it deeply, Use that understanding to carry the values you care about into the new world and re-articulate them. Make the car safer, push for tactical regulations on it. If you are privileged enough to be able to forgo its use entirely, sure, but that advice is not uniformly applicable. People forget that being able to simply opt-out of certain things is often only a viable option when you are already in a certain position. What we really need are the heavy skeptics to stop falling for luddite temptation and to start bringing their critical lens to bear in positive ways on this new technology to make it safer and better. By opting out and staging a feeble resistance you won't do anything other than let the current dangerous power consolidation continue.
