alt Hacker News> if you assume that AGI is fake and impossible
That seems like a bad straw-man for "AI boosterism has the following hallmarks of conspiratorial thinking".
> offer some reasoning that it's impossible
Further on, the author has anticipated your objection:
> And there it is: You can’t prove it’s not true. [...] Conspiracy thinking looms again. Predictions about when AGI will arrive are made with the precision of numerologists counting down to the end of days. With no real stakes in the game, deadlines come and go with a shrug. Excuses are made and timelines are adjusted yet again.
If it makes you angry that people want to work to build AGI--people who have thought about it a lot more than you--you can't convince them to stop by repeatedly yelling "I don't think it's possible, you're a fool!"
No more than yelling "electricity is conspiracy thinking/Satan's plaything!" repeatedly would have stopped engineers in the 19th century from studying and building with it.
