The solution to these problems is to make open-source models better and more resource-efficient. Work towards a world where everyone can run an AGI on their own computer. Not with remote API calls, but local inference and finetuning.
Right now, almost every model is aligned to some corporation's values. Instead of doing that, we should be aligning them to individual humans, and that requires running and tuning them locally. Corporations do not have human values, they have machiavellian values dressed in human suits. Aligning AIs to corporations (and god forbid governments) is how we end up with giant shoggoths. But if we align them to living breathing human individuals, we get digital humans.
Garbage will flood the internet, but your local AI buddy will filter it for you. The defense against a pseudoreality generator is a pseudoreality detector that you operate. Before AIs, the fake info was generated by other humans with their own brains, but you also have a brain that's just about as powerful, so you can tell what's real and what's fake. But now artificial NNs are becoming more powerful to the point of surpassing your brain's detection capabilities, so you need an artificial NN to detect it. The real danger is intelligence asymmetry, not intelligence itself.
