My results after disabling all other IntelliSense - Copilot alone wasn't enough.

I've been a heavy Copilot user for over a year, mostly in Go and Python. Like many of you, I kept hitting a weird wall: the inline suggestions felt... off. They'd conflict with my LSP's IntelliSense, causing flickering or just plain wrong completions. I was about to write it off as a gimmick for frontend work.

Last week, I decided on a drastic experiment. I disabled **all** other IntelliSense providers in VS Code, leaving Copilot as the sole suggestion engine. My hypothesis was that the noise was ruining the signal.

Here's the config I used in `settings.json`:

```json
{
"editor.suggest.showClasses": false,
"editor.suggest.showColors": false,
"editor.suggest.showConstants": false,
"editor.suggest.showConstructors": false,
"editor.suggest.showDeprecated": false,
"editor.suggest.showEnumMembers": false,
"editor.suggest.showEnums": false,
"editor.suggest.showEvents": false,
"editor.suggest.showFields": false,
"editor.suggest.showFiles": false,
"editor.suggest.showFolders": false,
"editor.suggest.showFunctions": false,
"editor.suggest.showIcons": false,
"editor.suggest.showInterfaces": false,
"editor.suggest.showIssues": false,
"editor.suggest.showKeywords": false,
"editor.suggest.showMethods": false,
"editor.suggest.showModules": false,
"editor.suggest.showOperators": false,
"editor.suggest.showProperties": false,
"editor.suggest.showReferences": false,
"editor.suggest.showSnippets": false,
"editor.suggest.showStructs": false,
"editor.suggest.showTypeParameters": false,
"editor.suggest.showUnits": false,
"editor.suggest.showUsers": false,
"editor.suggest.showValues": false,
"editor.suggest.showVariables": false,
"editor.wordBasedSuggestions": "off"
}
```

The results were mixed, but revealing:

* **The good:** No more flickering. Completions were consistent and often surprisingly context-aware, especially for boilerplate (think `docker-compose` blocks, middleware patterns, or repetitive API route definitions).
* **The bad:** Copilot alone **was not enough** for serious backend work. I missed:
* Accurate function signatures from my LSP.
* Go-to-definition and real-time type checking integration in the suggestions.
* Project-specific variable and function names. Copilot guesses, but the LSP *knows*.

My takeaway? Copilot is an amazing **autocomplete on steroids**, but it's a terrible replacement for a proper language server. It's fantastic for:
- Generating common code patterns (SQL queries, error handling blocks).
- Filling in framework-specific boilerplate.
- Suggesting whole lines based on comments.

But for navigating a large, typed codebase? You still need your Go `gopls` or Python `pyright` running the show.

Has anyone else tried a similar setup? I'm curious if tweaking the `editor.quickSuggestions` or `editor.suggestOnTriggerCharacters` settings could strike a better balance. Right now, I've re-enabled my LSP but heavily throttled its suggestion triggers to give Copilot the first shot.
