> If we assume that Oumuamua is an alien construct, what "new vistas of exploration for evidence and discovery" open up that we are not already pursuing? I think what he's trying to convey is that thinking of this object under the assumption of "aliens" pushes us to develop experimental technology to prove it. This could then lead to future advances (whether intentional or accidental) potentially helping us detect alien technology where we otherwise wouldn't be able to had we not begun that pursuit. He's looking at it from a very long-term perspective.
