I use GPT for AutoHotkey scripts for personal use. It fixes things Windows can't do natively. I used it briefly for a shell script on Linux but I don't use Linux much these days. When I used Linux daily I had a folder full of scripts I either adapted or copy pasted from the internet. I can't program but I can copy and paste and make minor changes to make a simple script suitable to me. GPT makes a big difference on my day-to-day, Windows 10 is under my control and I didn't need to learn AHK scripting. I'm not in IT, I'm just a regular person with a Hacker News account.
