Do you think a particular structure built in the 1900's or after will stand the test of time like The Great Pyramid of Giza. Honestly it feels like everything built after the industrial revolution(1760) was not built to last, it was just built quick. Especially now, things are getting cheap. I heard they're putting STYROFOAM in walls of some houses built nowadays. Also, skyscrapers and how they're currently built, are not made to last 1000's of years, and that seems to be the main structural masterpieces people focus on building nowadays. Fyi, I don't know much about architecture, I just always had this question & I wanted to ask people who know more about it.

Edit: scratch any building built in the 1900's. I just want to know if there are any buildings built anytime past the Industrial Revolution(1760) AND are still currently in use, like if it was built & it's still currently open to the public/ inhabitable & not some off limits tourist attraction site. I want to know if you think that building will still be around 1000's of years from now (obviously, it likely won't be inhabitable, but will it at least still be standing?). I am also interested in any buildings built in like 1980 or later that you think will still be around 1000's of years from now.
