I love how small, sleek handheld computers are so common now that we've had to invent new visual tropes to signify that people are using future tech. Transparent devices is a big one, like this:
These devices make so little sense from a user standpoint, though. None of your applications have a backgound, so you had better hope that whatever going on around you isn't too distracting. The bright lighting - necessary for your application this to even be visible, when there's no background - is something that people are trying to avoid
now. We have devices like Kindles, without backlights, and tools like Flux to dim our screens and remove blue light.
And worst of all, everyone around you can see what you're reading.
Maybe that's the actual prediction this trope makes: In the future, we've given up entirely on the idea that anything we do online is private. Your personal data is everywhere, and it's easy for anyone to look you up and see a comprehensive history. You know some tech bro monetized that idea as soon as advances in search technology made it possible. Capitalism collapsed, but the tech still exists.
So you don't give a fuck if the people around you know you're reading K/S whump. Your mom does!
