It drives me insane when science fiction movies and shows use transparent screens and phones, because like… that’s just a worse product for no reason? Why would you want a transparent phone?
My other pet peeve is holograms that are worse than just like… looking at a screen, or using a projector for a large room of people. Holograms could be cool for certain visualizations, but like… Maybe record a normal video instead of a blurry and pixelated hologram?
