Nine women can already have babies in parallel. That is, nine women cannot have a baby in one month, but nine women can have nine babies in nine months.

14,000 women will produce a baby in a month, because that is how many, in average, it would take for one of them to be 8 months pregnant. Of course, if you need one tomorrow, you can go over to the maternity ward and steal someone's that was just delivered.

Notably, his essay “no silver bullet” states that there has never been a new technology or way of thinking or working that has led to a 10X increase in the speed of software development. That was true for almost seventy years until roughly last year. AI is the silver bullet - my output is genuinely 10X what it was before claude code existed.

So there's input (prompts/requests/tokens), then there's outputs (lines of code) and there's outcomes. How much have the outcomes improved? Not just yours, but I'm more curious on the outcomes with regards to the actual need your projects are solving.

First counterexample that comes to mind: Rails vs 90s networked/shared line-of-business crud app development was a 10x factor. It also enabled a lot of internal tools that wouldn't have been worth doing without it. But after people's expectations adjusted it was just back on the treadmill. I don't think we've found a new steady-state yet, but I have some gut feeling guesses about where it's going to be.

In particular if that steady-state requires 4 to 40GB blob of binary code to be installed or an internet connection to an AI SaaS provider and a credit card.

I remember when coding was free as in beer and freedom!

That is far from proven, 'far' being the keyword here in another understanding.

At _this_ moment, AI is in the state of producing things - if you like with factor 10 or more. But what will come afterwards, when all this mush of code shall create _reliable_ results. This means not man month then, rather man years or decades to fix this billion and maybe trillions lines of opaque probabilistic LOC. You have to take the mean of these two stages, if nothing qualitative happens to the models.

I haven't yet seen anyone with a concrete example project (public ideally, but even describing private efforts in enough detail to enable potential criticism would be fine) making a claim as strong as 10x. Are you willing to break the mould and show us what we're all missing?

I can describe private efforts about a couple recent projects that made me finally believe that Claude Code can actually be a 10x multiplier on certain work.

We decided to integrate our SaaS into Microsoft Business Central and NetSuite as plugins into those systems. BC has its own programming language, called AL, that has a lot of idiosyncrasies from any other language I've worked with. And NetSuite plugins are written in SuiteScript, which is a custom JS runtime with a ton of APIs to learn.

In the "before", it would've taken 5 developers a year or more to build those integrations. I did both by myself in well under a year. Thank you Claude.

You’re describing output while the essay is discussing productivity.

If you’re 10x more productive, someone is willing to pay you 10x as much as they were last year, because you’re producing 10x as much value as before.

Has your salary increased 10x?

I don't believe the 10x claims, but since when has salary been any indication of productivity?

Here is a public project.

https://github.com/KeibiSoft/KeibiDrop

It took me 2 years ago around 2k hours to build a cross platform FUSE vault, without using AI assisted tools.

The pain was debugging through logs and system traces. And understanding how things work.

Now managed to ship this one much faster, as an after hours project. Started it in may 2025, and around end of November 2025 started using claude on it.

Just by dumping logs into claude, and explaining the attack vector for the problems, saved me the FML moments of grindings walls of syscalls on 3 platforms.

I would say much easier to progress, and ship with the same rigour, minimize my time, focus and brain power involvement such that I can put the energy somewhere else.

Yep, the real strength of AI is less in replacing engineering skills, it's more in slashing all the time we spend not using those skills and doing low level research and data correlation tasks instead. Which isn't to say that those tasks aren't valuable in their own way, but in terms of raw output...

It's interesting to revisit Brooks' "surgical team" in light of AI. For example, I frequently have Claude act as a "toolsmith", creating bespoke project-specific tools on the fly, which are then documented in Skills that Claude can use going forward. What has changed is that a) One person (or rather, one person-AI hybrid) plays all the roles within the surgical team, and b) Internal frictions such as cost, developmen…

How well does that work for you ? It's annoyingly inconsistent for me - I give it instructions on how to fetch JIRA ticket with a script that renders everything relevant to a .md and half of the time it will still default to reading it via ACLI. I have instructions on how to do a full build with warnaserror before commit but I still get pipeline errors regularly because it will skip the noincremental part, etc.
