Peak population estimates have traditionally come in at around 10-11 billion , so it would be welcome news if it turns out to be only 8.6 .

Your scenario is not entangled, it's just a lack of knowledge on the part of the other person .

Lack of knowledge is NOT the explanation of entangled particles.

I'd like to add that Newton and his contemporaries founded modern science -- the worldview that there is actually an objectively correct explanation for natural phenomena, and we can work on finding that out through thought and experimentation.

You will have noticed there are still many people today who don't hold that worldview, sadly; but in Newton's time and earlier, this described pretty much everyone outside of a select few, who were often considered heretics, witches, that sort of thing for their troubles .

Truth was what the church said it was and most people didn't have the concept of thinking about why apples fall, they just did. A large part of what Newton is remembered for is the notion of investigating this kind of thing at all .

(NB. My comment is Eurocentric like the question ; attitudes may have differed in other civilization centres ).

A lot of responses here saying "bruh findagrave" and missing the point of the project, which is to be able to quickly and easily locate a gravesite, especially in a large cemetery.

Findagrave profiles typically have plot numbers, which are somewhat tedious to translate to a location -- it can still take 10 minutes or more to find a location knowing the plot number; and sometimes the plot number was typed in wrong, or various different numbering schemes exist for the same cemetery. If you want to plan a tour of 10 graves that can take hours.

Furthermore, many have no plot information, and many more don't even correspond to burials (you can create a profile for anyone in any cemetery, and people do).

A minuscule few have GPS coordinates, which is a huge improvement and more akin to what this new project is doing; although there is no access to this data other than displaying coordinates on a per-profile basis, and pins on an aerial photo. The TOS also prevent scraping the GPS coordinates to make improved interfaces such as touted in this article.

A second major aspect is that there is little to no thoroughness or quality control on Findagrave. Mistakes will usually only be spotted when someone looking up their own relatives finds a mistake, and then has to go through the procedure of dealing with amateur profile managers who often have attitude problems and/or are unresponsive.

Thirdly, findagrave is a commercial project owned by ancestry.com and the crowdsourcing volunteers could see their work lost at any time; never mind the fact that their free contributions are already being monetized by Ancestry with no return to the contributors.
