I went from accepting I wouldn't see a true AI in my lifetime, to thinking it is possible before I die, to thinking it is possible in in the next decade, to thinking it is probably in the next 3 years to wondering if we might see it this year.
Just 6 months ago people were wondering if pre-training was stalling out and if we hit a wall. Then deepseek drops with RL'd inference time compute, China jumps from being 2 years behind in the AI race to being neck-and-neck and we're all wondering what will happen when we apply those techniques to the current full-sized behemoth models.
It seems the models that are going to come out around summer time may be jumps in capability beyond our expectations. And the updated costs means that there may be several open source alternatives available. The intelligence that will be available to the average technically literate individual will be frightening.
Bedroom superweapons? Algorithmic propaganda? These things have humans in the loop building them. And the problem of "human alignment" is one unsolved since Cain and Abel.
AI alone is words on a screen.
The sibling thread details the "mass unemployment" scenario, which would be destabilizing, but understates how much of the current world of work is still physical. It's a threat to pure desk workers, but we're not the majority of the economy.
Perhaps there will be political instability, but .. we're already there from good old humans.
In a general sense, uncertainty causes anxiety. Once you know the properties of the monster you are dealing with you can start planning on how to address it.
Some people have blind and ignorant confidence. A feeling they can take on literally anything, no matter how powerful. Sometimes they are right, sometimes they are wrong.
I'm reminded by the scene in No Country For Old Men where the good guy bad-ass meets the antagonist and immediately dies. I have little faith in blind confidence.
edit: I'll also add that human adaptability (which is probably the trait most confidence in humans would rest) has shown itself capable of saving us from many previous civilization changing events. However, this change with AI is happening much, much faster than any before it. So part of the anxiety is whether or not our species reaction time is enough to avoid the cliff we are accelerating towards.
