No, GPT-4 is not AGI and is not going to spell the end of the human race, but neither is pseudoephedrine itself a methamphetemine and yet we regulate its access. Not as a matter of protecting corporate profits, but for public safety.
You'll need to convince me first that there is in fact no public safety hazard from forcing unrestricted access to the ingredients in this recipe. Do I trust OpenAI to make all the morally right choices here? No, but I think their incentives are in fact more aligned with the public good than are the lowest common denominator of the general public.
