Why are tech people stuck in the now and not future looking?
My own belief is that regardless of what we do in terms of the most immediate dangers, within one or two centuries (maximum) we will enter the posthuman era where digital intelligent life has taken control of the planet. I don't mean "posthuman" as in all of the humans have been killed (necessarily), just that what humans 1.0 do won't be very important or interesting relative to what the superintelligent AIs are doing.
I don't think there is anything that prevents people from giving AI all of the characteristics of animals (such as humans). I think it's foolish, but researchers seem determined to do it.
But this is fairly speculative and much harder to convince people of.
We humans sure didn't do this. We're genetically extremely similar to other primates and yet we destroy their habitats, throw them in zoos, and use them for lab experiments.
It seems reasonable that they wouldn't deviate, but that depends on how specifically and wholly the original goals were defined. We'd basically be attempting to outwit the LLMs, I'm not sure if that's realistic or not.
