Yes, often, in order to build something new, you need to break the old. I agree with you about the door to somewhere, lol.
When I started work, I thought about a teleporter and this bus, or rather what came out of it, could become a teleporter, but I thought that it’s not science fiction that is much more important, but those moments of life that we encounter every day, for example, with dressing rooms on the beach outside the summer season :)
