What happened
A satirical npm package that left-pads strings by calling TypeSafe AI's Jev model instead of using JavaScript's built-in padStart(). It sends an API request asking the model to choose how many spaces to add (0-10 max), reads the choice, and concatenates. The author explicitly warns against using it in production.
Why it matters
This is a joke repo, not a tool to adopt. The useful takeaway is cautionary: if you're reaching for an LLM call where a one-line stdlib function exists, you're adding latency, cost, failure modes, and non-determinism for zero benefit. Worth showing as a meme during the segment to spark a quick conversation about where AI genuinely adds value versus where it's cargo-culted.
Discussion angle
Use this as a 2-minute icebreaker: ask the room to name the most trivial task they've seen someone try to solve with an LLM call, and draw the line between 'AI as glue for unstructured problems' and 'AI as expensive padStart.'
