Ask HN: Is writing code by hand still a necessary skill for developers?

Description

TLDR - My question is: For experienced developers, is writing code from scratch still a core skill worth learning? Is the future of development just using AI agents to orchestrate everything and just reviewing, debugging, giving specs, verifying, etc...? Rest of the information: I’m a full-stack "developer" trying to understand my career in the age of AI. I didn’t study CS, so I have a non-traditional background. I've also never worked with other developers until recently.
