Genuinely though, I found it a far less engaging, far less immersive experience than a normal 2D screen. Maybe the later models are better, I don't know, but I definitely don't see what the fuss was about.
I'm not sure what you're trying to imply there, but it seems a bit racist? Or am I just being ignorant?
I'm not trying to make any particular point with this story, just adding my contribution of an event that happened in the area.
From the initial "design" sketch to the use race-to-the-bottom design and coding websites, I was sure this was a parody of startups racing to sell a non-existent product with just vague ideas and generic logo.
std::vector<int> t = {0, 1};
t[0] calls operator[], which returns an int&. This is precisely an lvalue reference, which is kind of like a memory address, but int& is a type in its own right. Calling it a "reference object" is not entirely correct, but it's also not entirely incorrect. And let's not get started on vector<bool>...According to a book that I haven't read[1], but is cited by Wikipedia[2], "A 1949 study by Italian-American linguist Mario Pei, analyzing the degree of difference from a language's parent (Latin, in the case of Romance languages) by comparing phonology, inflection, syntax, vocabulary, and intonation, indicated the following percentages (the higher the percentage, the greater the distance from Latin): Sardinian 8%, Italian 12%, Spanish 20%, Romanian 23.5%, Occitan 25%, Portuguese 31%, and French 44%."

It looks like what the author is really trying to say is that we should pass the data through a high-pass filter, eliminating any 'expected' trends such as inflation, and instead observing if the noise of the two datasets is correlated. This is an observation that has some value, but is certainly not trivial to pick a threshold for the high-pass (certainly it's not always just a linear trend), and the mutually dependent variable can have as much noise (if not more) as the two measured data sources, so you still might get "false" correlation.
Anyway, yes, you've shown correctly that mod 7 arithmetic is useful, proving half the great-great-somethingth-parent's point. Now, the remaining interesting cases are the inversion case and the multiplication case, where 0 based is simpler (for me) than 1 based.
Also, the idea of using the word "octave" for "mod 7" is already pretty broken, and is what caused me my initial hesitation.
Maybe not for you, but it certainly took me a moment to convince myself that that is true.
