I wish an org like IEEE would be way more rigorous than what's revealed with the first paragraph: >In April, Microsoft’s CEO said that artificial intelligence now wrote close to a third of the company’s code. Last October, Google’s CEO put their number at around a quarter. Other tech companies can’t be far off. Take a moment to reflect -- a third of the company's code? Generative AI capable enough to write reasonable code has arguably not been around longer than 5 years. In the 50 years of Microsoft, have the last 5 years contributed to a third of the total code base? This itself would require that not a single engineer write a single line of code in these 5 years. Okay, maybe Microsoft meant to say new/incremental code? No, because Satya is reported to have said, "I’d say maybe 20%, 30% of the code that is inside of our repos today [...] written by software".

It's not his job to accurately report numbers, or really to do anything that involves technical acumen. His job is more akin to being a cheerleader, or a carnival barker.

Maybe they've had LLMs for a very long time, given the quality of their code...

They probably mean new code not the entire codebase, but even so I think those numbers are ridiculous given my experience. Is there any evidence of this (anywhere, not just MS or Google)?

  I'm not sure if it's ridiculous if you factor in something like copilot. Heck, even just your IDE's built-in autocomplete (which only finishes the current variable name) can get close to being responsible for 20% of your code, with tools like copilot I think you can even more easily hit that target.

They clearly mean "new" code. Meaning on any recent day, that amount of code is authored by AI.

      You know that because you're in tech. But the average person who is reading the news, and is likely to participate in a large protest in the next few years, would not naturally make a distinction between incremental and extant code.

      > “I’d say maybe 20%, 30% of the code that is inside of our repos today and some of our projects are probably all written by software,” Nadella said during a conversation before a live audience with Meta CEO Mark Zuckerberg. I think there’s some quibble to be made about “written by software” vs “generated by AI,” but it doesn’t seem like he’s talking about new code, right? He goes out of his way to phrase it “code that is inside of our repos.” It doesn’t really make any sense, but it does seem to be what he said. Maybe there was some context, maybe it is about some specific repos that was not included in the quote. But, it isn’t “very clear” in any case.

        It is "very clear" because it's not possible. He didn't go "out of his way"... it's live conversation, not something he could proof read and edit.

I've always interpreted that as "a third of the company’s (new) code" though I guess it would be nice of them to make that clear.
zack6849 1y ago
I'm pretty sure they meant 1/3rd of newly written code, obviously they don't mean a third of all their code that exists was written by AI

If a third of microsoft's code looks like this copilot generated PR [1] the company is going to go down the tubes soon. And I hope this happens, so, these corporate chiefs learn a harsh lesson when they are ejected for forcing stupidity across the org.

  https://www.google.com/search?q=msft+stock https://www.google.com/search?q=msft+stock They never did so well The issue with Copilot is that it is running GPT-4o and GPT-4o-mini, and both models are not good at programming.

newly writte code. But the consensus is that this is inflated numbers that don't involve the revisions that this code needs. Would be interesting for them to tell us what % of the LLM generated code gets thrown away .

I mean… it is objectively the truth to quote the CEO of MS as saying what he said, whether or not he is lying or using a misleading metric. The only questionable things about the quote, imo, are > Other tech companies can’t be far off. First, MS and Google are working on coding assistants so I’d expect them to be quite ahead of the curve in terms of what their CEOs report. Both in terms of what they are actually doing (since they have a bunch of people working there who are interested in AI coding assistants, surely they are using them). And in terms of that the head advertisers for these products, the CEOs are willing to say (although I should be clear, I’m not even necessarily saying he’s lying or being misleading. He’s in charge of a company that is advertising some AI tool, maybe all his reports are also emphasizing how good the dogfood is). Second and relatedly, quoting a AI tool salesman on how much of his company’s code is written by AI… eh, it is a big company, the CEO of MS is a known figure. But maybe they should be explicitly skeptical toward him. As you note, I wouldn’t be surprised if MS was itself far off from what he said in the quote, let alone other companies… Although, if he says: > "I’d say maybe 20%, 30% of the code that is inside of our repos today [...] written by software". Depending on how you look at it, that doesn’t necessarily preclude, like, classic macros and other classic code generation tools, so actually I have no idea what it even means. If an AI touches a JavaScript minifier, does it get credit for all the JavaScript that gets generated by it? Haha.

Are we really sitting here dissecting what he's saying as if it means anything at all for the future? 20% or 30% today is 100% tomorrow. That much is certain.

  100%? Certain? I disagree, strongly.
