Doesn't have to be for literal ever, just not until we (humans) blow ourselves up - if we don't achieve AGI until then, that's effectively ever. And you could gamble we'll blow ourselves up or make the planet uninhabitable before AGI.

And AGI is such an undefined word.

And don’t forget the moving goalposts. We still don’t even know what to expect from AGI. 100% perfection on 100% of tasks? If not then what?

Not really, humanity's time is very finite on a planet with finite resources. If we don't build it soon enough it won't get built.
