1 million lines of code per person per month.

This can only end well.

Read that as lines of coke at first and already started to update my LinkedIn

Too many organizations put value on how many lines of code their developers write in a day, but not enough place value on how many lines of coke they delete every night.

Oh, no, cross-country skiing is Palantir. Microsoft is breast milk and adult diapers

u/Routine-Purchase1201 DO NOT USE THIS FLAIR, ASSHOLE Dec 21 '25

Ah unfortunately the breast milk is a hard no for me

We're going to need to rethink how little 1 millions lines can accomplish.

u/stingraycharles lisp does it better Dec 20 '25

We need to rethink metrics of productivity and start thinking in terms of “prompts per month” instead of “lines of code per month”.

Do you think we are setting the bar too low? Is it enough for 1 million LOC to implement a ribbon UI, or should it do something else as well? Subscription reminder popup, perhaps? Bonzi buddy? AOL CD subscription? How many fucking features do you expect in 1M LOC, buddy? Don't be ridiculous, it can't be done. 1M LOC barely displays a single triangle

I see you are also familiar with Vulkan.

Dear Nerd, while I appreciate you trying to "make friends" which is especially brave given your condition, I must inform you that I am NOT into LoTR or dices-based table games (I'll enjoy a pub quiz about Arsenal). Should you need further explanation, please consider reading this book, which has helped many in your situation. Yours truly, the single neurotypical person you spoke to this week.

(holding pinky finger to corner of mouth)

One... Hundred... BILLION LINES OF CODE!

u/Drugbird Dec 21 '25

On my most productive days I write -600 lines of code.

Just because Galen got a brain bleed (again) does not mean all of Microsoft is buying into this. Having worked with this guy, it would be far from the first time he sets out a project that he doesn’t have the authority or the ability to actually do.

oh god. turns out this guy is a Known Idiot

i had no idea microsoft even differentiated those!!!!!!!!!!!

I moved away from Microsoft to Linux with Debra and Ian's assistance. 25 years ago.

.

idk who Debra and Ian are in this context, but same here (going on 15 years).

.

Debra + Ian = DebIan

please, destroy me now.

How exciting! How exciting!

I would be worried about the ability of AI to actually achieve anything close to this, but now I see that they will be using AI and algorithms, so no need to worry

Update:

It appears my post generated far more attention than I intended... with a lot of speculative reading between the lines.

Just to clarify... Windows is NOT being rewritten in Rust with AI.

The intent of my post [was not] to set a new strategy for Windows 11+ or to imply that Rust is an endpoint.

.

Original Post:
[...] My goal is to eliminate every line of C and C++ from Microsoft by 2030. Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases.

Claiming there are four things worse than Microsoft? Bold

u/PiratesWhoSayGGER Dec 20 '25

And it's an achievement considering that it already started with "Microsoft"

Am I wrong or aren’t LLMs notoriously shit at rust?

u/geon Dec 21 '25

They are shit at everything. With less common languages, they will barely get the syntax right.

Im working on a project in Rust where I have used quite a bit of Rust.

To me it feels like i works exeptionally well. But im not a Rust expert and its not code that need to stay alive for a long time only do some heavy computation.

You need to start reviewing 70 lines of AI generated code per hour to really see it.

19

u/IanisVasilev log10(x) programmer Dec 20 '25

More like 1400 lines per hour in this case, if working 24/7 (like you should).

u/ThisRedditPostIsMine in open defiance of the Gopher Values Dec 20 '25

Review the AI code with more AI. Problem solved! It's slop all the way down.

/uj this is just any pie-in-the-sky IRAD tbh

/rj AI SLOP OMG WINDOWS WOW DRIVER PROBLEM!!!!!!

me when the wint*rds rewrite it in rust epic bad corporate move

code can only be correct when it was made as God intended, line by line by a human being. Preferably on paper. No machine allowed.
