> “My goal is to eliminate every line of C and C++ from Microsoft by 2030,” Microsoft Distinguished Engineer Galen Hunt writes in a post on LinkedIn.

from the LinkedIn post [0]:

> I have an open position in my team for a IC5 Principal Software Engineer. The position is in-person in Redmond.

> My goal is to eliminate every line of C and C++ from Microsoft by 2030.

so perhaps a more accurate title would be "one guy at Microsoft, in a LinkedIn job posting, says it's his goal to replace all C/C++ code with Rust"

"“My goal is to eliminate every line of C and C++ from Microsoft by 2030,” Microsoft Distinguished Engineer Galen Hunt writes in a post on LinkedIn. “Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases"

What can go wrong? Yikes...

Fundamentally is there anything you can't write in rust and must write in C? With AI languages should mostly be transposable even though right now they are not.

Why rewrite something with multiple decades of validation and bugs-now-depended-upon-features?

Word and Excel almost certainly have 30 year old C++ code that #must-not-be-touched, bugs and all.

Anyone who's done some vibe coding can imagine what a mess a vibe coded operating system is going to be with current day tools. LLM agent coding is good at making small prototype web apps and the like but trying to apply it to significantly complex legacy software is a nightmare.

I'm not sure I'd feel comfortable making large changes to a complex legacy code base with just an LLM. But I think an LLM could be a big help to try to understand a complex legacy code base. As long as you are verifying what it is saying (which you would naturally kind of have to for that use case).

I absolutely agree with you. I think this quote in the article gave me the impression that they are talking more about vibe coding it at scale rather than llm assisted engineering.

  “Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases. Our North Star is ‘1 engineer, 1 month, 1 million lines of code.’
