I'm like you. I'd say my productivity improved by 5-10%: Claude can make surprinsgly good code edits. For these, my subjective feeling is that claude does in 30 min what I'd have dont in one hour. It's a net gain. Now, my job is about communicating, understanding problems, learning, etc. So my overall productivity is not dramatically changing, but for things related to code, it's a net 5-10%
