AI will always need certain machinery to operate, admittedly this doesn't mean bulky servers and huge desktops but it isn't it's own being and there isn't anything morally wrong with unplugging/destroying these machines like there is with a sentient being.
When people talk about the threats they aren't implying robots killing humans off en masse, but more that the potential for it to be used in many ways is huge, and the sensible approach is to prepare for this and consider the risks whilst it's being developed to try and minimise them. Once it's unleashed it can't be put back into the bottle, and even if there are strict rules around it's use unsavory characters will be able to use it. Kind of like the Internet, a wonderful tool which has absolutely changed the world; but lots of issues and problems that werent imagined at it's conception that could have been better planned for.
I do think (ironically) that some things will actually move away from tech in the dawn of AI (although chat GP isn't AI that sort of thing will continue to develop at pace). With AI being able to create art it still won't be able to have the same imagination and tools as humans have, I'd love to see a resurge in painting by hand and intricate designs and art. Students will probably move to either coursework under exam conditions or fully exams to try and mitigate cheaters. Manual jobs which can't easily be replaced will probably attract higher wages so the tide will turn a bit in terms of jobs deemed worthwhile due to pay.
Elon has a vested interested in encouraging restraint, I would bet him and his teams are still working on it in the background, the first to make the big breakthroughs will be very rich- also a political incentive much like the space race.
For sure it'll change things, it's actually still in a much less developed state than the media would have you believe- not all the changes and opportunities will be bad but as with anything it could be utilised for nefarious purposes. Its also not desirable for many governments to have their worker bees replaced.
