Building an AI Stock Market Prediction System That Grades Itself

I am building an AI system to predict the S&P 500. It runs on my own machine, uses free public data — yfinance, FRED, the Shiller dataset — and grades every forecast against reality. This series documents the build itself: the decisions, the methodology, the mistakes. What I will eventually share from the running system is a separate question, and an honest one.

AI sales forecast: 9 traps so far

Yesterday I could not tear myself away from the computer. When I lifted my head, it was half past eight in the evening. I had been sitting alone upstairs for about three hours.

Will AI take my job?

Will AI take my job? A certified Google trainer told me in June 2024 that my profession would cease to exist. Twenty-two months later, my job title has not changed — but ninety percent of what I do during the day is different. I have delegated more of my thinking to AI agents than I thought possible. I am not afraid. This is why, and what it means for anyone asking the same question.

A Year in Blogging: 2024

Blogging 2024: content growth and lessons

By Richard Golian

0:00 / 0:00

Writing is more than just putting words on a page. It’s those moments when hours slip by unnoticed, when I completely lose track of time, and when inspiration strikes at 1 AM, making sleep impossible until I capture my thoughts. Blogging is my flow, my way of processing the world, and my means of sharing ideas that might otherwise remain unspoken.

In 2024, I wrote 15 new posts, reached thousands of unique readers, and accumulated tens of thousands of views. But numbers are just a byproduct. What truly matters is the passion behind the words—the need to express and understand.

A Year in Writing

Each article I wrote in 2024 tells a story, marks a thought process, or captures a realisation. Here’s a look at the themes that shaped my year:

February: A Lifelong Relationship with Books

I began the year by reflecting on my deep connection with books, how they shaped my thinking from childhood, and the ones that have left a lasting imprint on my worldview.

April: A Shift in Perspective on AI

I explored how my understanding of AI had changed over time, realising that I had initially underestimated its role in certain areas.

€50,000 Quote vs. Two Hours with Claude Code

One hour. Fifty-five minutes. That is how long it took to build what a Czech software firm had quoted at over €50,000. I built it with Claude Code. Not a prototype. Not a proof of concept. A working tool — the one the company actually needed. By the evening of the same day, it was running on staging. This is not about Claude Code. It is about what Claude Code exposes.

Is AI Making Us Dumber?

I have conducted roughly one hundred and fifty practical interviews over the past four years. Fifty for data specialist roles. A hundred for advertising and performance marketing specialists. Almost every one of them involved sitting down with a candidate over a practical task — something close to a real problem we actually need to solve at the company. Not theory. Not trivia. Applied problem-solving. Over time, I started noticing a pattern.

What AI Hides From You

Before you can teach AI to understand anything, you need to see what it is hiding from you.

When Your AI Agent Joins the Team

The moment other people needed access to it, the problem changed completely. It was no longer about whether the agent could learn. It was about who gets to teach it.
