One problem for internet vs AI is the internet boom laid down a bunch of fiber, which has a usable life of decades. The AI boom is 10% datacenter, 90% GPU, and the GPUs are consumables on a timeline of ~3-5 years, and even that's being optimistic compared to rumored real-world degradation rates. 2000 put a couple trillion in the ground that we got to dig up later, 2026 is setting a couple trillion on fire.
