I knew 3 of the "valley" ones were valleys right away but have NEVER heard of "Uncanny Valley" so I was just guessing -- nor do I consider "iota" as relating to the concept of "one."
Maybe iota is a regional thing? I donโt give one iota is a saying I heard a long time ago. It has its roots in the Bible. The newer phrase โI donโt give a @$!@โ seems more prevalent today.
Iota is the Greek "I", One is roman numeral "I", etc.
And the Uncanny one, never heard of it. I had the three V's, and assumed it couldn't be Myself. So, I just started with the first one and got it. Had I missed on 3, I would have then know what the 2 groups were."]
