For sure a great infrastructure build out -- lets hope the leftover are better energy infrastructure so that whatever comes next in 7 years after the flame out has some great stuff to build on (similar to telco bubble 1.0) and less damaging to planet earth in the long arc.

Yep. The Telco Bust 1.0 along with the Dotcom Bust is what enabled the cloud computing boom, the SaaS boom, and the e-commerce boom by the early-mid 2010s.

I think the eventual AI bust will lead to the same thing, as the costs for developing a domain-specific model have cratered over the past couple years.

AI/ML (and the infra around it) is overvalued at their current multiples, but the value created it real, and as the market grows to understand the limitations but also the opportunities, a more realistic and permanent boo' will occur.
