this also happened with the internet. 6T is possible only if AI creates more wealth. same as with internet. Its not a zero sum game.
It isn't exactly not a zero sum game either though. If you want to sell something you have to have willing buyers with either funds on hand or sufficient credit to make the purchase. So yeah that 6T gotta come from somewhere.
Indeed, it is hard to say exactly how much wealth the internet creates, but it's a lot. E-commerce alone is $30 trillion industry; some estimates put the total economic value of the internet at $200 trillion or higher.
That said, this came too late for investors in the dot-com boom. AI investors may find themselves in a similar situation.
