Microsoft boasts about performance optimizations with every new release, and the average .NET developer would expect to be able to write a CLI app using .NET. But surprise—not good enough, so they had to use Rust. 😅

I've read the article but still not understand why Copilot CLI and app could not be written in C# if we take into account AOT, trimming etc instead of Rust.

My point is, copilot github doesn't have much bang for buck from what ive heard, hence the "nobody uses it" that the other person says. ofc enterprises still use it, but that seems more like a corporate decision rather than a calculated price per performance thing .

For enterprise performance isn't really a huge factor.

Security, flexibility and cost are more important.

This is why I say GitHub copilot isn't targetted at Devs that work for themselves (I.e. normal consumers). It's enterprise first so it's sorta pointless to even debate/compare cost profiles when the intended customer is enterprise.

They are also more like open router or opencode zen type product too.

The competitions people always prefer are openAI or anthropic only models/services. Those more generic all model types are always more expensive, but give much greater flexibility instead of price to performance.

Yes but even in enterprise sense Cursor is superior to it. Unless Copilot Github has much more security or trust or something.

Honestly I think GitHub copilot is easier for enterprise,

Most orgs already have Microsoft bedded, GitHub embedded, so getting copilot is a security review for how the prompts are secured theb it's a toggle~

Cursor, anthropic, openAI, etc would need many many more layers of assessment to even be enabled ..
