I am lucky enough to have survived two major earthquakes that completely destroyed my city when I was a kid. What’s interesting about those earthquakes is that the ground didn’t move side to side like you would expect. It actually moved up and down. As a result, lots of buildings were essentially ripped out of the ground and/or compressed into piles of rubble. My city had no skyscrapers back then, so we only got to see how the earthquakes damaged small buildings like houses. I’d love to see a video explaining what would have happened to skyscrapers during such an unusual earthquake.

I mean the video left out an extremely important point from the Kobe Earthquake, which is that the Japanese building codes were updated in the 80s but did not require retrofitting for single family homes. The primary buildings that collapsed were found to be the buildings that were built to the previous code and not retrofitted while most tall buildings were built after the earthquake codes had changed. So while the information provided regarding earthquakes and their interactions with taller structures may or may not be true the premise here is just not.

No, it's just that because of how many large buildings are affected by earthquakes they have added protections in their engineering where most 1-3 story buildings don't need it. Tall skyscrapers tend to be a much bigger investment and pose a much greater risk should they fail in comparison to a 2 story building. In his demonstration he also has the legs installed in opposite planes for the smaller building vs the larger which is why the effect seems so dramatic. Things like building materials and weight also come into factor, but really the concept of how the shaking affects higher floors is one of the biggest challenges. The best way to visualize it is to put a tennis ball at the end of a 6' pole. At the base of the pole move it a few ° and look at the distance the ball moves. That effect gets more and more amplified the farther away the end point is from the ground. But as far as the short vs tall comparison, I actually was a superintendent on building Apple's new amazing campus and the amount of proprietary tech in the building is unfathomable. The building is only 4 stories above ground and 2 below and shaped like a giant circle but because it's in California they build the entire thing essentially on a giant set of 6' wide ballbearings that allow the whole building to sway. Just looking at California as a whole there is also a reason why most buildings are only a few stories tall with the exception of specialized buildings in major cities.

You are being somewhat pedantic and somewhat missed the main point. Most modern tall buildings in first world nations tend to be safer. This assumes they are properly constructed to code. The main point is that the EQ forces on a tall structure are substantially less in proportion to the mass compared to short structure buildings. He also goes on to give an exception where the buildings are a long distance from the hypocentre of the EQ. This is what happened in Mexico city. The worse case is when the excitation frequency closely matched the fundamental frequency.

Anytime I hear something about earthquakes and skyscrapers, I think of the Millennium Tower in San Francisco. That's honestly the last building in the entire country that I'd want to be anywhere near during an earthquake -- and I certainly wouldn't want to be inside of it. The tower is still standing despite it's lean and the band-aid fixes have slowed down the pace of the sinking in the northwest corner, but I think it's far too late to save it long-term. Even if it wasn't located in the most geologically active region of the United States, I still wouldn't trust it not to eventually collapse.
