When it was built, it probably looked a little like:

I wonder what happened when the views were obstructed by the building next door.

Definitely in terms of "how is it possible that this building is not falling over". I remember first seeing 432 Park and immediately checking online to understand how it was physically possible to build. I'm still a bit skeptical. With increasingly frequent extreme climate events, I wonder how resilient the building will be.

It's had some problems, not sure how much the height is a factor

The aspect ratio is the problem. If it was steel it wouldn't be an issue but it's all reinforced concrete, flexing away in the wind on its spindly superstructure. In 50 years I'd expect it to be condemned.

If at some point it was deemed unsafe and impossible to fix, I am wondering how you could do a controlled destruction of it without damaging nearby buildings.

I guess you'd need to dismantle it floor by floor? Are there any example of very high skyscraper having been destroyed/dismantled on purpose, not by 9.11 attacks?

EDIT: found a table on wikipedia: https://en.wikipedia.org/wiki/List_of_tallest_voluntarily_de...

Most high buildings in that table were "deconstructed".

This one, at 46 floors, was the tallest imploded:

I remember trying to figure it out. It is 93' x 93' x 1396' tall, which is 15:1, while a cigarette standing on end would be 10:1

I wonder if the answer might be https://en.wikipedia.org/wiki/Dorf_on_Golf

"He is ... about as tall as a 5-year-old; his height and some humorous movements are achieved by Conway standing in a hole, with fake shoes attached above his knees."
