I can share an anecdote how slow tech adoption is in Korea. It is not exactly about tech in public section but in private companies. I assume public section has slower adoption rate than private ones in general.
Just about a year ago I had a couple of projects with insurance companies. I won't name them but they are the largest ones whose headquarters you can find in the very center of Seoul. They often called me in because I was setting up on-premise servers for the projects. Not to mention that it was hard to understand their choices of database architecture to plug it into the server I was setting up, their data team seemed just incompetent, not knowing what they were doing.
The wildest thing I found was that most office workers seemed to be using windows 2000 to run their proprietary software. To be fair, I like software UIs with a lot of buttons and windows from that era. But alas, I didn't want to imagine myself connecting that legacy software to my then project service. It didn't go that far in the end.
