smartphones
Explanation
The Joke
The comic opens with someone declaring that "Scientist: giving a child a smartphone is like giving a child a gram of cocaine." The next panel shows a child using a smartphone to do homework, clean the house, and research via "light researching appliances" -- all productive tasks. This is contrasted with the alarmist opening claim by showing that children actually use smartphones for perfectly mundane and even beneficial purposes.
The joke is a satirical take on the moral panic surrounding children and technology. Media and some researchers frequently compare screen time or smartphone usage to drug addiction, but the comic points out that the actual uses of smartphones are overwhelmingly ordinary and productive. The comparison to cocaine is absurdly hyperbolic.
The Humor
The humor works by juxtaposing the sensationalized rhetoric about smartphones being equivalent to hard drugs with the banal reality of how kids actually use them. The child is not spiraling into a digital abyss -- they are doing homework and looking things up. The comic mocks the tendency of cultural commentators to frame new technology in the most alarming possible terms, a pattern that has repeated throughout history with everything from novels to television to video games.
