Corporations have spent the last couple of centuries systemically harvesting profit from human lives by leveraging their concentration of capital, labor, intelligence, government influence, etc to transfer wealth to shareholders. Governments have used their monopoly on violence to enforce the extraction of taxes since the beginning of civilization itself. This has resulted in nearly every aspect of our lives becoming a profit or tax base for some powerful entity (especially so if you are an American, perhaps less so if you are Scandinavian).

Now we have reached the point where an emergent technology is about to further disempower natural born beings by devaluing the not yet already automated work which was the last beachhead upon which they could survive in the increasingly predatory economics of our current reality. The same entity structures (corporations & governments) will now control the most powerful technology ever created to serve their own purposes and goals which historically have not always been in the best interest of the rest of us.

It is an unpopular opinion here but maybe people are wise to be concerned given the track records of the players involved. Perhaps a rose tinted view of infinite prosperity for all emerging as an immediate result of AGI is not calibrated with the truth of human greed and ignorance. It will get much uglier before AGI delivers us a utopia.

No technological emergence which you have experienced is anywhere close to what is forthcoming. In a century every example you can point to today will be considered just a stepping stone to this.
