I wasn't implying that they'll fill every building with interiors though if you look at my reply, I just pointed out a fact. I agree on the fact that by looking at the reply above, mine might be interpreted in a certain way but that's not what I meant. The one implying what you disagree on is the guy who wrote the main reply I replied to

I didn't expect my reply to draw so much attention, I just wanted to make other people aware of a tech CIG is working on but I wasn't implying anything

Anyway, during the demo ST didn't say that those could be used just for rest stops, and in the reply you linked he implies that they could theoretically fill buildings relatively easily but they don't need to fill all of them, not that they can't do it. They'll probably use that tech to create interiors for the missions planned to be executed inside ArcCorp's skyscrapers

I myself don't expect every building to be filled with interiors and I'm ok with their current plan but if they did it procedurally you wouldn't probably need to render everything because you'd probably render just the room you're in at any time, if you were flying above ArcCorp you'd just load exteriors
