Spoiler theory - So Bernarnold wakes up on the beach...

And foregoes his glasses because he is now fully Arnold and Ford internalized. When Strand tells the foreign military soldiers to get off his island, those military figures are actually hosts with Dolores and other woke hosts marble muffins installed, and that is why Ford, talking through Bernarnold, mutters "I've killed them, I've killed them all" he is referring to the rest of modern humanity that is effectively the next generation of Neanderthals that are going to be "eaten" by our new robot overlords.
