The dangers of AGI I don't think are very related with consciousness or sentience (maybe the saddest outcome if it killed us all and weren't at all).
I'm still catching up on my reading, but the existential risk of AGI as I understand it is chiefly that we don't know how to align AI (and keep it aligned) to be beneficial/benevolent for humanity, but the risk is contingent also on a few other things things - that we develop AI that agentic and able to develop and pursue it's own goals and sub-goals, and that it has power-seeking or game-theory strategic awareness/planning. The extra dangerous situation is if it is better than humans at making better AGIs and allowed to improve itself (or build its successors).
Regardless of when we reach AGI, I think the alignment issue is a key one for both AI ethics and safety. As for the rest, while they aren't necessarily things that will happen, since it seems to the first thing people most want to build - the other day, the top three projects on https://github.com/trending were all projects to try to make ChatGPT autonomous/agentic.
FWIW, I don't think the 6-month ban is a good idea, but I also think there's a lot of xrisk w/ AGI and it's better to be thinking about it seriously sooner, rather than later. What I've been reading:
