1. Auto-complete makes me type ~20% faster (I type 100+ WPM)
2. Composer can work across a few files simultaneously to update something (e.g. updating a chrome extension's manifest while proposing a code change)
3. Write something that you know _exactly_ how it should work but are too lazy to author it yourself (e.g. Write a function that takes 2 lists of string and pair-wise matches the most similar. Allow me to pass the similarity function as a parameter. Use openai embedding distance to find most similar pairings between these two results)
