There are many animes based off of true stories o have a slice of life theme that they might as well be a reality. Many animes have had Live Action o musicales done for them. I think the best one I have seen is the Death Note Drama. But I would not wish for anime to be a reality because humans would abuse any power they were giving and life would be más apocalyptic.
anime is awesome and to be honest i believe we go through life as if it is a game(refer to sword art online and btoom) unfortunately we all must awake eventually 😞 after all if we were all our favourite anime/manga/movie/book/etc.then we would all be pretty stuffed
