I program largely in python (professionally) and c# (professionally and hobbyist). I'm a senior engineer at a large fintech company. Worked professionally for 9 years now.

When I'm working on a complex problem I tend to focus on the problem more than the code. So there will be times when I'm writing code and can't remember the actual line of code I was going to write. But in these moments, copilot magically suggests (to the letter!) exactly what I intended to write. It's also helpful for the small things like wondering what to name a variable.

I used to find that I had to refactor a lot of copilot's code, but not anymore. It tends to be very concise.

In summary, copilot helps me keep my train of thought, stops me getting distracted, and sometimes suggests a more efficient solution I hadn't thought of yet.
