I more or less agree with the article but we can move it one step further. Nowadays we don't even need text editors no matter how advanced they are. I am a VS Code user and I have not opened VS Code in more than 3 months because I don't need it anymore. Opening a text editor and editing code by hand seems like so ... yesterday.
This definitely is a new era and, personally, I love it! (Also I have broken my right arm so I can't write code even if I wanted to. I'm dictating this text.)
Emacs is not an advanced text editor, it's more like an OS. I run Claude Code inside emacs (with the claude-code-ide package). I seriously think LLMs will usher in a new golden era for emacs because you can now reap all the benefits without having to learn elisp.
I mostly use Emacs not to write code, though. In fact, getting Claude to do explorations for me and output its findings as org docs is fantastic.
I was saying almost this same thing to a coworker. I'm building something that's like Emacs, but for agents, and it's mostly a Markdown-forward tool for managing all the agents and agent coding harnesses, and it's a vendor-agnostic things....If anything it's like a newer, faster, fancier org-mode, but knows how to inject all the right context into all the agentic projects.
This, after configuring Emacs to talk to LLMs. But that's not the right angle now for me....
