To be fair, Github Copilot (itself a horrible name) has followed the same arc as Cursor, from AI-enhanced editor with smart autocomplete, to more of an IDE that now supports agentic "vibe coding" and "vibe editing" as well.

I do agree that conceptually there is a big difference between an editor, even with smart autocomplete, and an agentic coding tool, as typified by Claude Code and other CLI tools, where there is not necessarily any editor involved at all.

all of these companies are going to follow each other's UX patterns for the rest of time.
