Doing some worldbuilding. Human beings don't seem to be handling the computer era well. We see improvements in some ways, and problems in others.
One concept that came up - smartphones having both broadband internet and video cameras means that if someone acts cringe in public, it can be blasted on the Internet and spread across their social circle in moments, which makes it more dangerous to take socially risky acts in public - which is many social acts in general when someone is inexperienced!
Using fertility as a crude proxy, things got weird in the 1970s, but were more normal from 1989 to 2009.
Digital video existed in 2001. However, it relied on either dedicated digital cameras, for shorter videos, which required planning to bring with you (making them less likely to show up at random times), or digital camcorders (which are a bit unwieldy and are very obvious).
If technology rules in a zone prohibited smartphones but allowed dedicated digital cameras or digital camcorders, with appropriately large housings, should it use modernized electronic components in a bulky housing, or old-style components that are inherently bulkier?
Well, wouldn't teenagers take the miniaturized modern-style components out of the bulky housing and use them to make a hidden camera?
This one turned out to be easier than I thought.
Thinking about it (and I am not an electrical engineer), it should be possible to make the circuit boards larger, while routing some of the wiring close to the edges, so that it requires some electrical engineering work to successfully cut the boards down to size. This would not alter the weight of the device much, because circuit boards are thin and are often made out of fiberglass.
