Every new generation changing technology is followed by a frenzy of infrastructure build out.
Running up to the dotcom bubble lot of money was spent on building undersea cables and Internet infra because the assumption was that the demand for websites was going to be a straight line if it not exponential. There was an over capacity of expensive infra. Then the market crashed and the same infra went for cheap and laid foundation for Internet as we know today.
Same thing happened during the railroad frenzy in the 1800s.
And same thing is happening today. There is assumption that the pace of AI improvement and demand is going to be straight line if not exponential. So lot of money is being spent on data centres looking at “future”. There is going to be an oversupply of expensive hardware and models because who doesn’t want that sweet AI money.
Sooner or later the market is going to reset because nothing can keep going up forever. It’s only after the reset we are going to see the upsides of AI.
