I do think there’s a real risk of Brain Atrophy when you rely on AI coding tools for everything and while learning something new. About a year ago, I dealt with this problem by using Neovim and having shortcuts like below to easily toggle GitHub Copilot on/off. Now that AI is baked into almost every part of the toolchain in VSCode, Cursor, ClaudeCode, Intellij, I don't know how the newer engineers will learn without AI assistance.
