That result does not show up for me when I google it and the other one is the top result for me.

If someone can come up with a reason why top results aren't even present on others' page 1, I would be very interested.

Google "personalizes" search results.

> I am aware the search results can be different to different people and based on demographic information.

You answered yourself. If you are are searching zoos and cute animals more often than programming stuff, "python egg" will return dramatically different results. This is not a theoretic possibility, it is the way google works (which I think is unfortunate).

What a time to be alive

The scare quotes are disingenuous. However we may dislike or disapprove of Google's algorithms, it is absolutely accurate to describe the results as personalized.

They individualize search results: they give different results to different people.

They don't personalize search results: they don't give people results which are optimal for the searcher, but rather those which attempt to be optimal for the advertisers without discouraging the searcher enough to swap search engines.
