Add in the fact that GPT-4 does not "think" very fast, has no arms or legs, needs to run on expensive specialized hardware, and essentially seems like a search algorithm that lacks creativity on things outside of its training set, and I just do not see the concern. Maybe GPT-42 will actually be more creative and adaptable than a human genius, but even then, this seems like a hypothetical problem for the 2050's, less pressing than "accidentally igniting the atmosphere with nuclear chain reactions".
Hollywood has instilled the idea that the first time an artificial intelligence becomes self aware and decides it wants to take over the world, it will immediately be successful.
The serious concern and scrutiny should only start stifling progress once we have some evidence of half-baked attempts by non-super-intelligent AI's attempting to subvert their boundaries.
I for one am very excited to use GPT-5 and see more useful tools coming from OpenAI.
