I stopped reading at "load-bearing" and em dash.

Ironically, the prevalence of AI "tells" like that (combined with the ubiquity of AI works passed off as human-written) will inevitably feed back into more use by non-AI writers who think they're normal.

(Also, I'm never gonna give up my em dashes.)

Open-source alternatives are being launched at an ungodly pace and they are really polished. All these comments about AI Slop are underestimating how good these builders have gotten and AI lets you iterate really fast. If the builder actually uses the software he's building, the feedback loop is really efficient.

I keep a directory of open-source alternatives and just in the past month, I've replaced applications I've used for years with open-source alternatives.

What open source alternatives have you switched to recently? Always on the lookout for good OS tools!

The zero-cost fallacy: open-source software in the agentic era. Here's my thoughts on this. It's back to open source, not open maintainer or open usage. I am producing lots of new code, i am publishing it. I am NOT interested in starting a project or having other people contribute. It's a cambrian explosion, the cost of adding features is basically zero. I'm going with "patching software is more common and we need to…

> the cost of adding features is basically zero

Adding features was always the easy part. Maintaining the code OTOH is not going to be easier.

I see this with an experimental project I’m consciously vibecoding. The code base tends towards a spaghetti coded mess.

Of course you can put in some refactoring prompts and the AI will reorganize the code. But that makes it worse actually.

You have no mental model of the code and after a large refactoring even less.

I recently read Eric Raymond’s The Cathedral and the Bazaar. It was oddly sad to read. The enthusiasm and optimistic view of open source and the future of software and craftsmanship. Looking at it in 2026.. incredibly sad. Forget the bazaar. Back to the cathedral.

Nothing that was possible then is less possible or less potent now.

The narrative is not friendly to communities of people owning complex software by sharing work now, but neither was it then. If you believe it was all wrong, an incorrect formulation, then disregard it and do not despair to move on. If you think ESR got something right that nobody can see anymore, then your hope should be rooted in the knowledge of how much less than what's possible we are currently achieving

Both of these are true: we’re witnessing an unprecedented amount of slop, while also the tools get better and better.

So when talking about Open Source maintainer exhaustion, it’s because of the slop, not because of the great tooling.

AI is an amplifier, and in this case it amplifies the great asymmetry between contributor and maintainer.

People need to stop yelling "Slop!" all the time and saying silly things like "every line of code was reviewed by a human". First, it's ridiculous. There is no possible way to verify that claim, determine what was or wasn't done after reviewing it, and there's no reason to review every single line. It's performative. I have a ton of stuff I haven't bothered contributing. Why? So I can deal with all the hate? When it was "many hands make light work" there was value in sharing the load. Now I've got a backhoe and it's not worth the hassle.
