William Gibson (author of Neuromancer among other things, not all of them good) published an article about Singapore 30 years ago. It's titled Disneyland with the Death Penalty: https://librarianedge.pbworks.com/f/William+Gibson+article+on+Singapore+1993+--+Disneyland+with+the+Death+Penalty.pdf

33 years later and much of this is still very relevant. It has dated somewhat, but accurately reflects what I experienced in Singapore during work travel over the past few years.

At the least, if you're interested in what dystopian science fiction writers think about Singapore it certainly dropped some puzzles pieces into place for me.
