America's railroad boom isn't a great example, it got us the worst rail infrastructure in the world, built by private monopolies solely for maximum short-term profit, i.e. moving freight and not passengers, and now American industry is largely gone and we're stuck with rail infrastructure that is useless to almost everyone and it costs far more to maintain it than it's even worth. America's internet infrastructure, like the railroads, was also left in the hands of private monopolies and it is also a piece of shit compared to other countries. It's slow and everyone pays far too much for it and many are still excluded from it because it's not profitable enough to run fiber to their area. The AI bubble won't leave behind any new infrastructure when it bursts. Just millions of burned out GPUs that get sent to an e-waste processing plant where they are ground up into sand, trillions of dollars wasted, many terawatt hours of energy wasted, many billions of liters of freshwater wasted, and the internet being buried under an avalanche of pseudorandomly-generated garbage.
