During the dot com bubble, telecom companies spent 10s of billions of dollars laying down cables and building out the modern public internet infrastructure that we are still using today. Even if a lot of companies failed, we still greatly benefited from some of the the investments they made.
For this bubble, the only long term investment benefits seems to be the electricity build out and a renewed interest and investment in nuclear.
Most (if not all) of Oracle's investments are mostly in chips and data centers.
