>but perhaps the scale of it is not as large as the internet build out?
In the past 5 years 5 times as much GPU compute capacity has been installed as total CPU capacity that has ever existed. When it comes to capital intensity the growth of AI has been one of, if not the largest capital expenditure for a class of project in this short of time frame. Things like the Manhattan project which was absolutely monstrous expense at the time is dwarfed by this.
Of course measuring GDP growth is difficult when you have an idiot in chief trying to destroy the global economy with the dumbest set of actions contrived by a human ever. Disentangling this factors will take a lot of work on someones part.
