What's this about?
Responding to the week's most-liked developer tweet, Mollick argued that "explain like I'm five" is the wrong default. The real advantage of these models is that they work as universal translators across topics, so asking for a generic dumbed-down explanation is worse than asking for a personalised one: "explain to me drawing on what I know."
What exactly is the difference?
ELI5 discards complexity to reach a general audience. Personalised explanation routes the idea through what you already understand — explaining monetary policy to a plumber via water pressure, say. The second is strictly more informative, and until recently it was impossible at scale because it required someone who knew both the topic and you.

- The core argument is that ELI5 throws away the model's most distinctive ability in exchange for a familiar format.
- The defence of ELI5, implicit in its popularity, is reliability: a fixed phrasing that always works beats a bespoke one you must construct each time.
- The synthesis several readers reached: use ELI5 for things you know nothing about, and ask for personalised explanations once you have a foothold.
