This Pub is Launching Paid Subscriptions: What Changes, What Doesn't
Independent AI research stays independent.
First, thank you.
In just a few months, A Mathematician Lurking in the Tech Underworld has grown to several hundred free subscribers—readers, commenters, and people who share the work.
That growth came with no marketing budget, no algorithm hacks, and no corporate backing.
It came from applying serious mathematics to the hardest problems in AI—and making those ideas accessible beyond a closed circle of private research dominated by a small technical elite.
Now we need your financial support to keep this independent AI research alive—research that can say the emperor has no clothes without asking permission from an industry-captured boardroom.
Today I’m launching paid subscriptions. Here’s exactly how it works:
What stays free
Every article’s core argument.
The diagnosis.
The what and the why.
If your goal is to understand what is broken in AI’s mathematical foundations—and how it can be fixed with the right mathematical and engineering tools—the free posts give you that, fully and openly.
What’s behind the paywall
The how.
How to apply the right mathematics and engineering to solve real AI problems—not just to understand them, but to fix them in production:
Implementation insights for real production systems
Code and algorithms
Technical notes as they are developed—unfinished, exploratory, honest
Priority responses to technical questions
This is the depth engineers need to actually apply these ideas, not just agree with them.
The price
$5/month or $50/year.
Many engineers expense technical publications through their company’s learning budget.
If that’s you, this is mathematics that may save your team from committing to the wrong AI architecture.
Founding members — $150/year
Personalized, in-depth responses to your technical questions
Named acknowledgment as a founding supporter of this research
Why this structure
I want the ideas to spread. Free readers get the full argument.
But turning ideas into working systems takes deeper work: original research, real implementations, code, and sustained technical exploration.
That work is what paid subscriptions make possible, and what paid subscribers gain access to.
Subscriptions keep this research independent.
No sponsors.
No institutional filters.
No pressure to soften the critique.
The same depth and independence that brought hundreds of readers, engineers, and supporters here over the past few months, that is what I intend to protect.
For everyone else: nothing changes.
Keep reading.
Keep questioning.
