Why Vim Refuses to Become VS Code

Main summary

Key takeaways

Technology

Technology focus: “Editor Wars” are really about philosophy

The video argues that the Vim vs. VS Code debate is less about text editing and more about where complexity should live:

  • VS Code: pushes complexity into the tool, so users need less memorization and precision.
  • Vim: pushes complexity onto the user, keeping the editor fast, predictable, and powerful once learned.

Vim: history and its defining interaction model

Origins on Unix terminals (1970s–1990s)

Early Unix systems had limited compute power, expensive displays, and slow networks. Editing therefore leaned toward command-driven tools, such as:

  • ed (Ken Thompson)
  • ex (Bill Joy)

These ideas evolved into vi and later Vim.

Modal editing

In Vim, keyboard input is not simply “type letters.” Keys generally behave as commands depending on the current mode:

  • Normal mode: keys = commands
  • Insert mode: keys = text insertion
  • Visual mode: selects text
  • Command-line mode: complex instructions

A common illustration: the “can’t quit easily” joke—requiring explicit commands like :q!.

Editor-as-language idea

Vim treats editing as a kind of structured “language” where commands can be composed to delete, change, move, and transform text efficiently.

Efficiency model: muscle memory

Vim emphasizes minimizing hand movement (keyboard as a control panel) and building muscle memory over time.

Feature evolution

Over the years Vim added:

  • Syntax highlighting
  • Multiple windows
  • Scripting
  • Improved undo
  • Extensive customization

Project/community details

  • Vim is free software (GPL-compatible).
  • Bram Molenaar is credited as a key maintainer and encourages donations related to children in Uganda (mentioned via the International Children’s Fund).

VS Code: platform and integration approach

Origins (Microsoft, 2015)

VS Code was created as a lighter, cross-platform, free editor, designed to scale through:

  • An extension marketplace (rather than shipping everything by default)

Implementation technologies

VS Code uses web-adjacent technologies:

  • JavaScript/TypeScript
  • Desktop shell: Electron (related to Chromium/Node.js lineage; referenced alongside Atom)
  • Editing component: Monaco

“Self-explaining” onboarding UX

The video emphasizes VS Code’s newcomer-friendly interface:

  • Sidebar file tree
  • Git indicators with color
  • Underlined errors
  • Graphical extension browsing
  • Integrated terminal (with shortcuts)
  • Debugger UI

Language support is largely extension-driven (examples listed include Python, Rust, Go, Java, C#, Docker, Kubernetes, databases, remote servers, etc.), along with IntelliSense suggestions based on language understanding.

LSP (Language Server Protocol): bridging the worlds

The video highlights that LSP (standardized/created with Microsoft’s involvement and used in VS Code) separates “language intelligence” from the editor:

  • Language servers provide completions, symbol navigation, refactoring info, and diagnostics through a shared protocol.

As a result, Vim/Neovim also adopt LSP, narrowing the feature gap.

Neovim modernization (since ~2014)

Neovim has pursued features more typical of modern IDE workflows, including:

  • Asynchronous operations
  • Lua configuration
  • Built-in LSP support mechanisms

Result: Vim-family editors can gain “modern IDE features.”

Remote development: cross-pollination again

  • VS Code added remote workflows (SSH, containers, WSL).
  • Vim historically already fit the Unix/terminal model for remote editing.

The argument: both ecosystems increasingly borrow strengths:

  • VS Code keeps the UI local while tools run remotely.
  • Vim works anywhere a terminal exists, increasingly enhanced by modern protocols.

Architecture and “where complexity sits”

Unix philosophy vs “workbench” philosophy

  • Vim/Unix approach: combine small specialized tools via shell commands (edit/Git/grep/compile).
  • VS Code approach: become a “place where these systems meet,” offering an integrated IDE-like workflow.

Workspace-centric integration

VS Code is designed to concentrate:

  • Version control
  • Debugging
  • Language services
  • Extensions
  • Notebooks
  • Remote access
  • AI assistants

into one environment.

Ecosystem and economics differences

VS Code

  • Free editor, but strategically tied to Microsoft services:
    • GitHub ownership
    • Azure
    • Copilot distributed in the editor
  • Benefits from an open-source foundation plus Microsoft-branded distribution.

Vim/Neovim

  • No single corporation controls direction.
  • Plugin ecosystem from independent developers (Git workflows, navigation, UI enhancements, file management, etc.).
  • Tradeoff: freedom can create downsides such as:
    • Heavy customization
    • Plugin conflicts
    • Brittle configurations
    • Update breakage

Neovim also accelerates a “platform-like” ecosystem through Lua-based plugins.

Performance/resource criticism

A key criticism: Electron vs terminal editors.

  • Electron-based apps like VS Code generally use more CPU/RAM than terminal editors like Vim.
  • Critics frame this as wasted compute.
  • Proponents argue VS Code’s extra features justify the overhead.

AI as a renewed fault line

VS Code + Copilot

Copilot is described as transforming VS Code from a passive editor into something that:

  • suggests code
  • explains and generates features
  • helps with larger tasks

Vim/Neovim with AI

AI can be used in Vim/Neovim too, but cultural expectations differ:

  • Vim tradition emphasizes precise user control of text.
  • AI raises a question: should the user still manage character-level edits manually?

Two extremes (as framed in the video)

  • VS Code extreme: the editor should understand intentions and automate most work.
  • Vim extreme: user control and skill are the value.

The video concludes that software needs both automation and skill.

“Convergence” despite the controversy

The final claim is that the boundary is less fixed than it appears:

  • VS Code users can emulate Vim keybindings.
  • Vim/Neovim users can adopt:
    • LSP
    • fuzzy search
    • Git UI
    • debuggers
    • autocompletion
    • AI assistants

It also describes a trend of mutual borrowing:

  • VS Code learns more “Unix-like” remote behavior.
  • Neovim becomes more integrated/IDE-like.

Bottom line: acceptable friction

Editor choice becomes a question of how much friction you accept:

  • VS Code: more tool complexity, less user learning.
  • Vim: more user learning, while the editor stays simple/fast/predictable.
