Human coder here. First problem: define what is “writing code.” Well over 90% of software engineers I have worked with “write their own code” - but that’s typically less (often far less) than 50% of the value they provide to their organization. They also coordinate their interfaces with other software engineers, capture customer requirements in testable form, and above all else: negotiate system architecture with their colleagues to build large working systems.

So, AI has written 90% of the code I have produced in the past month. I tend to throw away more AI code than the code I used to write by hand, mostly because it’s a low-cost thing to do. I wish I had the luxury of time to throw away code like that in the past and start over. What AI hasn’t done is put together working systems of any value - it makes nice little microservices. If you architect your system as a bunch of cooperating microservices, AI can be a strong contributor on your team. If you expect AI to get any kind of “big picture” and implement it down to the source code level - your “big picture” had better be pretty small - nothing I have ever launched as a commercially viable product has been that small.

Writing code / being a software engineer isn’t like being a bricklayer. Yes, AI is laying 90% of our bricks today, but it’s not showing signs of being capable of designing the buildings, or even evaluating structural integrity of something taller than maybe 2 floors.
