Re: I'm struggling here
This is all assuming that it's worth the effort to create all of this 3D content. A DIY store selling kitchens to people would have to pay people to create a sales pitch to a huge number of people that will likely be "just looking" and not ready to start making payments on a new fitted kitchen.
The example of having an engineering meeting with people from all over a country or the world narrows down the market to very large companies which is narrowed down even more to very large companies with engineers on the same projects not being at the same facility. I worked at a place like that and it was very dysfunctional. I don't think it's a matter of how good the tech is, there is a benefit to having people physically in the same place to work on a project or to play a board game.
