The AI Investment Boom

Reading this makes me willing to bet that this capital intensive investment boom will be similar to other enormous capital investment booms in US history, such as the laying of the railroads in the 1800s, the proliferation of car companies in the early 1900s, and the telecom fiber boom in the late 1900s. In all of these cases there was an enormous infrastructure (over) build out, followed by a crash where nearly all the companies in the industry ended up in bankruptcy, but then that original infrastructure build out had huge benefits for the economy and society as that infrastructure was "soaked up" in the subsequent years. E.g. think of all the telecom investment and subsequent bankruptcies in the late 90s/early 00s, but then all that dark fiber that was laid was eventually lit up and allowed for the explosion of high quality multimedia growth (e.g. Netflix and the like).

I think that will happen here. I think your average investor who's currently paying for all these advanced chips, data centers and energy supplies will walk away sorely disappointed, but this investment will yield huge dividends down the road. Heck, I think the energy investment alone will end up accelerating the switch away from fossil fuels, despite AI often being portrayed as a giant climate warming energy hog (which I'm not really disputing, but now that renewables are the cheapest form of energy, I believe this huge, well-funded demand will accelerate the growth of non-carbon energy sources).

Why? The rail network, road network and fiber network that was laid could be used for decades after their original investors went bust.

The current datacenters full of AI compute can't really be used for anything else if AI companies go bust.

That's the problem with investing in compute infrastructure - you need to have a plan to use it all up in the next 5 years, because after that you wouldn't even be able to give it away.

The renewable power infrastructure for those datacenters will still exist.

People will be able to buy those used GPUs cheap and run small local LLMs perhaps. A 10 year old computer today won't do state of the art games or run models, but is entirely acceptable for moderate computing use.
