Yes, I've had similar experiences recently and similar thoughts. Crossing land borders in Asia is more stressful than it was a few years ago. Lots of redundant security theater and biometrics everywhere. Of course, China is on another level to everyone else. At the immigration booth, your conversation with the official is now translated and subtitled in real time on both sides. And face ID is now so universal in China that I suspect the fingerprinting has become an afterthought. Everyone is being filmed and tracked pretty much everywhere. Not just cash but even ticket numbers are now redundant. Everything is attached to your personal ID and cameras decide whether you enter public buildings, train stations and so on. The day their government decides to really abuse all that power, they're in deep trouble.
In my experience the border thing is clearly worst in Asia, but with the exception of China it's mostly just tiresome theater.
By contrast I crossed into the Schengen zone from Turkey this summer and was surprised by how little security there was. But then I noticed the police all but dismantling a bunch of heavy goods vehicles in their search for illicit migrants. That was absolutely not security theater.
PS. This subject got me thinking. I've seen a ton of borders because I like to travel by land. Different regions of the world definitely have different priorities at borders. In Asia it's drugs and contraband. They care what's in your bag. In Europe and North America, it's you they care about: why you're here and when you're going to leave. In police states like China, borders are a golden opportunity to harvest a ton of data on suspect individuals. In much of the rest of the world, Latin America for example, borders are mainly just an employment scheme, bureaucracy for its own sake.
