The cruise industry is very fascinating to me. I think in the medium term we could see significant populations of people living long-term on cruise ships; it seems like the economic model is long-run more efficient (assuming the shipbuilding industry is very good at building these structures). You avoid the property tax, zoning, and regulatory burdens that go with living on land. It's likely safer because you're not driving cars and you don't let criminals onboard. And Starlink solves the internet access problem.
