Apple Photos in the last year has been no small update, but also in the High Sierra also improved.

From Safari to Metal 2, the shadow of artificial intelligence is looming in this update. As Crag Federighi said:

I hope that more and more people will discuss how Apple uses machine learning and artificial intelligence to make the system more intelligent, AI should not be understood as Siri.
