Yes, IDEs of the future will not look like those we have today. I too started with Cursor and similar VS Code enhanced IDEs. And ended up using Claude Code. And realised my terminal is more important for me now. So I migrated from iTerm to Ghostty (faster, lighter, more modern), Tmux and Tmuxinator, and NeoVim! Because I just cat/bat files and occasionally edit a file, if at all. Claude Code does the heavy lifting, I write specs and prompts, in NeoVim or Emacs. And I am loving my workflow.
I too use Claude Code for more then just generating code. Whenever I need to rewrite a config file (for zsh, neovim, ghostty, etc), I start Claude code and assign the task to do it. It will do the changes and even refactor my settings file in a few minute.
Lastly, I use it to ask questions about my codebase, refactor code, let it document my code, even make meaningful commits.
Pure awesomeness.
