The comparison to completion time of the Empire State Building, the Great Pyramid of Giza, etc, are dishonest. Those weren't completed by a single individual, so it doesn't make sense to compare it to all time spent by each person watching the video.

For a fair comparison, you should also count the time that people "waste" visiting those imperial derelicts.

In the case of the Eiffel Tower, it has received over 250 million visitors. Assume that people spend an hour per visit, that's around 30,000 years wasted visiting the Eiffel Tower.

Now that's a super interesting snippet. Despite existing for far longer than Gangnam, the Eiffel Tower has only entertained twice as long total as Gangnam. Technology has democratized access to experiences.

I was thinking the same thing. First one I saw was for the Eiffel Tower, which took 300 people 2 years, so that should actually show as 600 years, not 2.

Not to mention the time required to design it, the time spent by workers to collect the raw materials used to build it, the time spent in factories to produce a finished metal product that could be used in construction, etc.

Attempting to calculate the man-hours that went into almost any project of scale is absurd. There are far too many factors to consider.
