The "goal" of AGI seems to be a pretty subjective thing, doesn't it? Idealistically, I could believe that the goal of AGI is to help humans build the future faster, and expand our footprint beyond what we currently believe is possible. Your pessimistic view of AGI is definitely valid, but it doesn't make it anything more than opinion, just like my view.
AGI is being developed by companies which have billions to fund it, such as Google, Meta, and Microsoft. Their goals are not subjective. These are ruthless for-profit entities that exist to increase shareholder returns.
If the goal with AGI is to literally take all of our jobs (all jobs in all sectors) then what are you suggesting we can do instead?
