NY times has a new material about possible observations of UFOs by air force pilots. Should rationalists use their arsenal of new ideas about how the world works – simulation, superintelligent AIs etc – to explain these things, or should they be of more sceptical side and explain them via some combination of biases and hoaxes?
For example, one could speculate that an alien AI have terminated long before now, but some of its self-replicating robots colonised the universe. Or may be we live in a simulation which is full of glitches and viruses?
It is possible to create many hypothesis like these with infinite explanatory powers.
