In the next 10 years, we expect to begin seeing more objects like' Oumuamua. The LSST will be leaps and bounds beyond any other survey we have in terms of capability to find small interstellar visitors, we may start seeing a new object every year. That's when we'll start to know whether' Oumuamua is weird, or common. If we find 10-20 of these things and' Oumuamua still looks unusual, we'll have to reexamine our explanations.
