Adding the time dimension solves the issue. The price of "AI from two years ago" will be cheap, and the price of "state of the art AI" will be high. You already see this happening today, and it is in many ways the economic history of technology thus far anyway.
The situation should result in large percentage increase of world GDP growth rate compared to current rate, but it's hard to know exactly how high as it depends on various bottlenecks that might be hard to foresee right now.
