A work colleague had a tedious operation involving manually joining a bunch of video segments together in a predictable pattern. Took them a full working day.

They used "just" ChatGPT on the web to write an automation. Now the same process takes ~5 minutes of work. Select the correct video segments, click one button to run script.

The actual processing still takes time, but they don't need to stand there watching it progress so they can start the second job.

And this was a 100% non-tecnical marketing person with no programming skills past Excel formulas.
