I don't believe "true" agi/asi will happen, but I totally believe if a company theoretically invented they would immediately shut all API's and then go for software market dominance in every category.
While I've said in another comment on this thread that comparative advantage is flawed, I still think the opening moves, the very initial phase, would be as per comparative advantage, not everything all at once.
Until supply grows to saturate demand in whatever market, comparative advantage points to the fastest way to make more money, that money then gets used to construct more servers and data centres, which gets used to saturate supply for the next most profitable market, etc. until there's none left.
I wouldn't say "never" for AI that can economically substitute all human labour. I think that meaning of AGI/ASI is slightly easier than the "AI which learns from as few examples as humans do" meaning, which I also think is possible eventually but don't know how far away it is.
