I love this school of thought (if you want to call it that)! It seems like a very reasonable and simple answer (considering what advanced technologies other lifeforms could have) to why we haven't seen any concrete evidence anywhere yet. My personal favorite theory for your question of 'when?' is that it actually has nothing to do with reaching a physical point in our universe. Instead, we make some advance that either A) allows us to perceive another dimension/energy that we couldn't before, or B) raises our consciousness to a level to match what should be the tons of aliens in space. Always fun to think about!
