Not OpenAI, but Anthropic CPO Mike Krieger said in response to a question of how much of Claude Code is written by Claude Code: "At this point, I would be shocked if it wasn't 95% plus. I'd have to ask Boris and the other tech leads on there." [0] https://www.lennysnewsletter.com/p/anthropics-cpo-heres-what...

This guy is so full of shit. Anthropic’s leadership are all talk and hype at this point. And they’re not the only ones guilty of this in this hype cycle by far.

I don't disagree it's a naive take, and I would love to read about some examples where this happened. I haven't seen too many industries be automated away first hand, and I'm sure there are historic examples. I wouldn't expect the lamp lighters to have been championing the rise of electric lamps. Maybe they did though because it meant they could work less hours.

Software developers have been automating away software developers since the beginning of the field. Higher level languages, better+safer languages, improved IDEs. All the ways in which we made developing software easier and more efficient. QA teams investing in automated testing.

At some point, if this process continues, it is expected to actually automate software developers, would you agree?

Software engineering has also been automating its own jobs for ages. The first thing we engineers do when asked to do a repetitive thing is find ways to automate it. I think the industry had qualms about losing their jobs. But honestly what are the examples of people losing their jobs to software ? Everybody says that this has happened many times yet examples are hard to come by.

> But honestly what are the examples of people losing their jobs to software ? Bank tellers Travel agents Cashiers Bookkeeping clerks Typists

Many of these still exist today, though is not as large of numbers. Maybe it's the same for software engineers. I still don't recall hearing of bank tellers accelerating the pace of ATMs or Travel Agents encouraging their clients to use Expedia.

I think this is the wrong question. The right question is how much human code can a human push now vs prior to AI. Everything we've done in coding has been assisted. Prior to this current generation of web applications, we had the advent of concepts like Object Orientated Programming and prior to that even C was a massive move up from Assembly and punch cards. AI has written a lot of code. AI has written very little…

>I think this is the wrong question. Why? It is a perfectly legitimate question where the answer is some sort of a percentage.

You write an essay in bullet points then you put the essay into ChatGPT to clean up and then you edit the output again before sending in the essay.

Who wrote the essay and in which percentage?

I'm pushing like 30-50% more code per week since using AI, and I'm only really using Cursor.

That's an anecdote, not a citation. How are you measuring your output before and after you started using Cursor?

This can be solved by using Levenstein distance or doing some funky calculations involving a diff-like algoritm that git uses for example. It is by no means a hard problem to solve.

In the year 2025 the primary job function of all C-level execs is marketing. Which is to say, he probably doesn't know the actual number, doesn't care, and is just saying what he knows the "right" answer should be.

This is like asking me "how much of your software is built by the compiler?" -> the answer is 100%. Ask "how much did you build then?" -> also 100%. The compiler and I operate on different layers.

Did you refer to any code from GitHub or other sources online?

I don't work at Open AI but I use Codex as I imagine most people there do to. I actually use it from the web app not the cli. So far I've run over 100 codex sessions a great percentage of which I turned in to pull requests. I kick off codex for 1 or more tasks and then review the code later. So they run in the background while I do other things. Occasionally I need to re-prompt if I don't like the results. If I like…

Do you use any tools to help with the code review part?
