AI is more akin to a zero sum game. It won't add 10% to the global economy (and if it did - it would be around "peak of inflated expectations" and, likely, have a corollary slide down into the "trough of disillusionment") because it will both distract budgets and/or redirect budgets. That hypothetical $7T is not coming out of thin air. I'd even go as far to argue that this hype cycle will ultimately detract from global economy over time as it's a significant draw on resources that could have been / would have been used on more productive efforts long term.
