If true, and complex life evolved more than once on the same planet, then it is much less likely as a strong candidate for the great filter [1].
So, very roughly, either life is hard to get started at all (but life started about as soon as possible on earth), intelligence is hard to evolve (although we see many species with intelligent behaviour, if not at human level), or it's in our future (that intelligent life tends to destroy itself).
