The difference being that a lot of millennials know how to figure out how to do stuff on computers by doing basic research. I’ve found a lot of my Gen-z friends to be more helpless in that regard.

Don’t pretty much all modern .zip managers know to not open zip bombs anymore?

If they were going fast enough for that to happen they would be launched toward the front of the ship anyway, and we don’t see that happening.

But most people don’t live in most places.

I don’t see why it wouldn’t be a market for all the buildings around it too?

It’s very common to have grocery stores in the bottom floors of buildings that are open to everyone, not just the residents of that building. And in parts of Europe it is the norm for large commercial/residential buildings to reserve the bottom floor for small retail businesses. It would greatly improve cities to have this.
