The fact that technology is still accelerating and we are seeing technology that used to be a sci-fi thing only, like holograms or whatever this shit is kinda scares me shitless, especially since there is no proletarian state controlling the direction of research which is instead aimed at "lol I saw this in a movie once, it might be cool" a la Elon M*sk, causing some rich fools to do stuff that both holds us back as a species (like commercial spaceflight for the sake of getting William Shatner to space) and actively endangers us (whatever this shit is, or the insistence on individualistic solutions to climate change like electric cars)
