Copilot is great but I think the media overstates how much productivity gain it's giving software engineers. Let's just say it's true that it's writing ~50% of the code but it's not the same as only need half the size of engineering team - most of our time is spent on not writing code.

Copilot is not really that great. Not compared to GPT-4.

The only problem is externality pricing.

Yup. I just got access to Copilot Chat (nightly), curious how that compares.

Using both works well. Have GPT generate a class, module, component etc. Then tweak/polish it in editor with co-pilot assist (it has more context about the project).  I used this last week and it saved me quite a bit of boilerplate work. The tools will continue to get better.
