I’m wondering about this. I mean lot of time at least in our company’s software I first have to think about how to implement a feature because it might effect many places in the app. Lot of time is going into design then usually writing the code is just small part of the equation. It’s really hard for me to believe that 50% productivity claim from Copilot. I write TypeScript and I think it support that and maybe I’ll try it out.
Edit: It wasn’t 50% it was close to 30% source: Research: How GitHub Copilot helps improve developer productivity - The GitHub Blog
