Monday assorted links
1. The real secret and meaning of The Beatles.
2. Large-brained humans have been around longer than we had thought?
3. Tallest bridge in the world opened, with coffee shop at the top.
4. John Searle, RIP. And a defense of John.
6. DeLong on AI and existential risk.
7. Secretary-General of NATO says it is Russian drones. I guess that is what you would expect when they have no transponders on, do not respond to communications, and have no records of landing or taking off at other airports?
