>Less than 5% of a programmers time is spent physically writing code

Not sure where you work at, but I am a principal SDE with 16 YoE and even though I spend most of my time in meetings, helping more junior team members or just on communication in general I try to shoot for 40-50% of my time actually writing code and Copilot does help with that (I'd say maybe 20% productivity increase). Even our dev manager probably spends more than 5% of his time writing actual code (but most dev managers don't of course).
