But if you insist...here are two very small examples from my personal experience with AI tools.
1. I work as a technical writer. Recently I needed to add a summary section to the introduction of a large number of articles. So, I copied the article into ChatGPT and told it to summarize the piece into 3-4 bullet points. Were I doing this task a few years ago, I would have read each article and then written the bullet points myself – nothing particularly difficult, but very time-consuming to do for dozens of articles. Instead, I used ChatGPT and saved myself hours upon hours of mundane work.
This is a quite minor and mundane example, but you can (hopefully) see how this will have major effects on any kind of routine text-creation.
2. I am working on a side project which requires the creation of a large number of custom images. I've had this project idea for a few years, but previously couldn't afford to spend $20k hiring an illustrator to make them all. Now with Midjourney, I am able to create essentially unlimited images for $30-100 a month. This new AI tool has quite literally unlocked a new business idea that was previously inaccessible.
