Reflect. A mirror.
Is it knowledge (gleaned from the world) or just a reflection?
Well if you're looking straight at it then it's pretty obvious whether it's a mirror or not. But add a couple of filters and suddenly you're having a conversation with yourself like a crazy person.
In trying to find a reputable source, the first result was to an HN comment… that I wrote.
The folks we were playing with were not convinced.

Google knowledge panel's answer: "Harry S. Truman".
The correct answer is Bill Clinton, born in 1946.
Truman was president from 1945 to 1953, so he was the first president in office during the actual baby boom, when the Baby Boomers were babies. So there seems to be a connection, it's just totally the wrong one.
> The first baby boomer president of the United States is Bill Clinton. He was born on August 19, 1946, which places him within the demographic cohort known as the baby boomers.
