The AI agents do a lot more than write code though. They can summarize meetings and emails, prepare project plans, create interactive design mockups, keep track of what you work on and write weekly/monthly summaries, create reports based on A/B test data, etc. If someone is heavily using AI, coding is just one part of it.
I use it quite a bit for planning and partially implementing side projects at work. Stuff that isn't my normal day-to-day project. They're usually APIs or internal webapps that I'd find useful but don't have time to do all the work myself.
For example, we use Google Chat at work, but its management of custom Emoji isn't great. I created an internal tool that shows all custom Emoji sorted by how frequently they're used, and allow people to vote on deletion (since we have a bunch of duplicates). I used AI to plan it, build the entities, write the code to hit Google's API, etc. I had it running in the background while working on other more important projects.
I treat it like an intern or a new grad. Assume the code won't be great, but I can guide it to do the right things.
