Phones can easily be oriented either way, unlike most laptop and workstation screens.
Majority of views certainly come from people whose eyes are horizontally next to each other and therefore whose field of view has a greater extent in the horizontal rather than vertical direction.
Admittedly I don't understand where the vertical recording fad comes from. Personally I take pictures and photos that are almost exclusively horizontal except in rare cases like taking a picture of a very tall building.
The US has extended the protection of the law to the law-abiding Irish, Italians, Germans, Russians, Jews, East Asians, Indians, and Latinos freeing them up to flourish and build human capital. By contrast, the same state has not only failed to do so for the Black community, but its agents have engaged in extrajudicial killings of the community's members with impunity since they lost their legal "protection" as someone else's private property.
Community under assault will redirect its private efforts to security which then undermines cultural and economic development and slows down formation of human capital. That's because security needs are fundamental and trump cultural and economic development [1].
Regarding Indian Hindus, Sikhs and Muslims, I disagree they are indistinguishable for outsiders. Typically, anybody who cares can tell by the name, place where they live, or even just the job they do.
Well, the may have understood the concept of "running out of stuff" and yet not realize it naturally belongs with numbers (of which they would have known other examples like one and two). I can imagine ancient folks putting the notion of "running out of stuff" with ideas such as "hungry", "empty", "dead" etc. Formation of the more abstract concept of zero-the-number is certainly a few cognitive experiences further down a line.
The perspective of modern computer science (with its zero-based indexing etc) or modern algebra (with its need for neutral element for addition) certainly makes it clear that zero is just another integer. However, without those perspectives I doubt it is so obvious.
For example, people normally count things by starting from one, so, at least following this usual procedure, counting to zero is technically speaking impossible. Also, we can't distinguish between zero apples and zero oranges, but we can tell two apples and two oranges apart.
In fact, even with the perspective of modern algebra zero remains special. For example, it is the only element of a field without a multiplicative inverse.
I'd be surprised if zero didn't take any extra effort to discover. It's clearly different than other integers.
The OP said "There's more time between the last Stegosaurus and the first T-Rex" which computes to 145-72 = 73 and "then (sic) there is between the last T-Rex and us right now." which computes to 66-0=66. Note that 7 million years is about 10% of the timescales involved, so perhaps not something to be dismissed as "scientific error".
