I never seen AI being used in writing system software. Perhaps there is a reason behind it?
Personally I have been making Velocity Proxy plugins for Minecraft where ChatGPT generates the bulk of the plugin and I fix all the incorrect imports, this is Java. My latest project was a whitelist plugin that uses Discord roles to allow/deny players to join.
Also, one major thing I'm missing personally is automatically generated OpenAPI specifications + API documentation & API clients autogenerated from it. Last time I checked Go, you had to write the spec manually, which is just ridiculous — the code already has all the necessary info, and duplicating that effort is time-consuming and error-prone (the spec says one thing, the code does another). This may be out of date, but if it still isn't, it is enough to disqualify the stack completely for me.
Also, I don't think there anything similar in the Go world to these administration panels:
https://docs.djangoproject.com/en/5.1/ref/contrib/admin/
https://activeadmin.info
https://nova.laravel.com
which are just fantastic for intranet projects and/or quick prototyping.
I am actually using this for a production site that gets 1 million requests per day.
