I share my thoughts, personal stories, findings, what I am working on, and what I learn from the people I meet, on technology, finance, politics, and the questions I cannot stop thinking about.
Four days in Catalonia without a computer or AI confirmed it: the digital middle stopped working. Here is the system that replaced it.
Read →How to blog in the age of AI? Being a secondary source no longer makes sense to me. I write as a primary source, because no machine and no algorithm can replace a unique experience.
Are we too dependent on AI? Through Hegel’s master and slave, why AI leaves us worse off than the master who knows nothing.
Sixteen of twenty-seven sources in one consulting report did not check out. AI slop that looks finished, and why big firms cannot police it.
Seventy per cent. That is where the first AI output begins, even with full company context and the best past examples. Someone simply has to sit at that computer. Without that it does not work, and for now it will not.
The dead internet theory: most of what you see online is turning AI-generated and the internet is becoming a game full of bots. Will part of us return offline?
A senior marketer rejected AI after one bad result. Others automate everything. The gap between professionals in the same field is wider than I have ever seen.
A Russian drone hit a block of flats on EU and NATO soil, the 28th breach. Russia fired 54,500 drones at Ukraine in a year. Why Europe is falling behind on drone defence.
AI makes the graphic, the newsletter, the product page. Judgement over the result is what remains. Can AI learn it too, and is yours the kind that survives?
What determines a stock price? I decompose an S&P 500 or sector fund price into six components of stock valuation and teach it to my AI prediction system: book value, earnings premium, macro, events, media attention, and…
What happens to money when AI takes most of the work? A six-layer map of the coming economy: who pays whom, where capital concentrates, where to stand.
Four days in Catalonia without a computer or AI confirmed it: the digital middle stopped working. Here is the system that replaced it.
Can AI predict the stock market? Not with point precision. After four years tracking market moods in a spreadsheet, I am building a calibrated prediction system on my own machine.
I am teaching an AI agent to forecast orders. The first version was 10 % off. So far I have found 9 hidden traps.
Will AI take my job? A Google-certified trainer told me it would. Twenty-two months later my job title is unchanged, but ninety percent of what I do is different. Why I am not afraid, and why most fear is misplaced.
A Czech software firm quoted more than €50,000 for a simple customer-facing tool. With Claude Code, I built the same tool in one hour and fifty-five minutes. This is what that gap reveals about software pricing, AI agent…
After 150 practical interviews for data and marketing roles, I noticed a pattern. Candidates with AI access consistently underperform those from three years ago who had none. The AI productivity paradox is not theoretica…
AI models hide their system prompts, training data, confidence levels and alignment decisions from you. Eight layers of concealment, from hallucinations to corporate RLHF instructions, and what it means for businesses de…
What happens when your team gets access to an AI agent? Role-based access control, shared memory, and the question most teams skip: who gets to shape what the agent knows.
What is an AI agent? I built one that is autonomous, then hit the real problem: AI agent memory. Here is how persistent memory lets it learn between sessions instead of starting from zero.
Local AI explained from real use: what Ollama is, how I ran a local LLM on a Mac Mini, where it broke, and why I moved to Claude Code.
Slovakia was once the fastest-growing economy in the EU, the Tatra Tiger. In 2026, it records the slowest GDP growth in the V4. What happened to Slovakia's economy, why companies are leaving, and what could reverse the d…
How attention is manipulated through outrage, fear and information overload. A clear explanation of agenda-setting, attention economy, Cambridge Analytica and modern political influence.
Great Fatra and the Low Tatras form the mountain heart of Slovakia. Wild nature, bears, long ridge hikes and the Jasná ski resort in one region.
Running a local AI model reminded me of discovering web development as a kid. A short reflection on curiosity, flow and the early days of a new technology.
That model is based on a simple question: if I take a certain risk, how much can I gain, and how much can I lose? And is that ratio in my favour? In finance, this is called risk–reward.
Are you making your own decisions, or are you being guided? This article maps how evolution, technology, and power intersect to manipulate human behaviour, from food and fear to political marketing and disinformation. A…
On searching for cyclical investment opportunities in the stock market at a time when growth stocks and indices are expensive and expectations are high. A reflection on sector cycles, book value, risk–return balance, pat…
My personal top 3 places in Slovakia: historic mining towns Banská Bystrica, Banská Štiavnica and Kremnica, the High Tatras and Lomnický štít, and modern Bratislava.
Big players like the US and China treat us as second-class partners. It is hard to watch.
Where do I invest today? I reduced my stock market exposure, redirected capital into strategic raw materials, and started restoring a family home. Not every investment is financial.
Ultra-processed food quietly made me ill for years. Chronic stomach pain since childhood, bloating, fatigue, poor sleep. Doctors found nothing wrong. Then I stopped eating ultra-processed food, and every symptom disappea…
I recently heard an idea about the future that lodged itself in my mind and hasn’t left since. It was about artificial intelligence and how it might reshape our need for mental effort. The thought came wrapped in an anal…
Is AI making investors obsolete? Capital used to be essential. Today, one person with AI can build in a weekend what once took months. If creation costs approach zero, what is capital still for?
Why is Slovakia one of the most pro-Russian countries in the EU, yet deep inside NATO and the eurozone? A clear take on Slovak politics and its contradictions.
Why was the European Union created? For peace. The USA was built on freedom. China on restoration. Russia on greatness. India on unity. These purposes seem incompatible. Dialogue is the prerequisite.
So let me remind Mr. Fico of the history he conveniently forgot or does not wish to acknowledge. When he speaks of the Second World War, he seems to overlook when and how it actually began.
The AI knowledge gap is bigger than anyone admits. Most working-age people have never used a language model. The gap between surface awareness and deep AI literacy is growing fast.
Could AI job losses trigger a stock market crash? When millions of middle-class workers who also invest lose confidence in their economic future, the sell-off follows, driven by psychology, not fundamentals.
The idea that artificial intelligence could, paradoxically, liberate us from robotic work imposed on us by past revolutions does not always land well with everyone.
I often get asked what I am doing with my finances this year. My answer is simple: almost nothing. Back in December and January, as I have written on this blog before, I gradually increased the cash portion of my portfol…
Vibe coding means building software by telling an AI what you want in plain language. I am not a developer, yet I used vibe coding to build my own cookie-free, GDPR-compliant web analytics tool with AI. Here is what vibe…
Correlation vs causation: two things moving together does not mean one causes the other. After years of A/B tests and performance marketing, I distrust confident talk of certainty and causality. Here is what the differen…
Not long ago, we had a team meeting at work. We were addressing a recurring issue, not just a one-off slip, but something that felt systemic. The atmosphere was strange. Quiet. We asked everyone to speak up if they knew…
We are about to enter earnings season for Q1 2025, and this time the numbers might carry more weight than usual. For the first time, they will reflect the impact of something that swept across Europe earlier this year, a…
What is artificial intelligence? It predicts the next word; you understand through lived experience. The real difference from human intelligence, explained.
How to focus? For me it began with changing my daily rhythm: a fixed 7:30 start, the quiet hours before colleagues arrive kept for deep work, and the most demanding thinking done before noon. Here is the early morning ex…
Today, I realised how dramatically AI can help in investigating criminal activities through the analysis of publicly available information. This topic has caught my attention. When I think about it, investigators, journa…
Many people today fail to grasp the risks that come with the rapid advancement of AI and robotics. It is time to ask the hard questions: What scenarios await us in the future? How do we prepare for them, and how should w…
A cognitive bias is a systematic error in our thinking, and I keep seeing one form of it everywhere: we no longer think, we just consume. Candidates arrive at interviews with metrics pulled from ChatGPT that they cannot…
Performance marketing isn’t just about ads, data, and analytics. It’s about identifying weak spots, recognising potential, and making the most of it. It’s a continuous process of learning, testing, and optimisation. Thos…
The more I think about the future, the more I realise how many essential questions remain unanswered. Maybe I am wrong, but it feels like our imagination simply is not enough to grasp what lies ahead in five or ten years…
What is the meaning of life? To me, it is the endless drive to understand the world, to build deep relationships, and to consciously choose who I become.
What is the meaning of life when AI handles everything? Drawing on Heidegger's concept of existential anxiety, this essay explores human purpose in the age of automation, and why the answer will not come from machines.
Which jobs will survive AI? The real question is what people will truly need in ten years. Water, safety, meaning, community. Can a robot care for the elderly with empathy? The future of work depends on us.
What if we are only weeks or months away from the moment when new technologies, in the wrong hands, test the fragility of banks, stock exchanges, pension funds, and other financial institutions? What if one morning we wa…
A flow state is the short-lived condition of total absorption in a task, where time disappears and performance peaks. I explain what a flow state is, how to get into one, and how it differs from hyperfocus and autistic s…
We live in an era where the accuracy and speed of information are incredibly valuable. The opposite of that – poor use of information, inaccuracies, or misinterpretations – significantly increases the likelihood of disas…
Europe not only has potential but already boasts incredible tech companies shaping the future. To realise this potential, we need to raise awareness about our achievements, develop a more robust capital market, and creat…
Do you know what the Cyclically Adjusted Price-to-Earnings Ratio (CAPE) is? If not, you probably should. Right now, we are at levels reminiscent of the dotcom bubble at the turn of the millennium.
To everyone who has read, shared, and engaged with my blog last year. Thank you. Your thoughts and feedback make this process even more meaningful. Here’s to another year of learning, questioning, and writing.
It is not just about what we deliberately input into AI. Our interactions with chatbots also reveal our knowledge, problem-solving abilities, and thinking patterns. Essentially, this creates a database of the intelligenc…
Returning to Slovakia after spending time in Prague, I immediately felt the growing division that has gripped the nation. Under Robert Fico's leadership, policies such as questioning Slovakia's EU membership and shifting…
Long-term thinking is not a strategy I picked up. It is how my mind works. Here is how I apply it to my work, finances, personal growth and relationships.
Visiting my sister Kristína after some time, I was struck by how many more paintings she had than I remembered. Her space felt transformed, almost like an art gallery. Her paintings were everywhere, not hung on the walls…
What is philosophy? Having studied it, my answer is that philosophy is the love of wisdom: the rational pursuit of understanding the world, the human being, and how they relate.
During the prime-time news, the report confidently claimed that the growth of the S&P 500 index was directly tied to the growth of corporate earnings. Accompanied by charts of recent stock price developments, this narrat…
From this moment forward, I’m treating my health as a top-priority project. This means making a comprehensive to-do list, setting clear deadlines, and holding myself accountable. I need to listen to my body’s signals, pr…
Is the stock market overvalued? When I analyse sectors individually, the optimism puzzles me. I increased my cash position, not from fear, but from reflection.
When reflecting on my greatest strengths, I do not point to talent. As I have written before, I do not see myself as exceptionally gifted. I know people who are more talented than I am. But what drives my progress is som…
In 2019, when I first learned about Volt Europa, a movement dedicated to driving positive change across Europe with a distinctly innovative approach, I was immediately intrigued. Volt Europa stands out as the most forwar…
From an early age, I recognised that I was part of a larger, interconnected world.
What do I look for in potential colleagues? Good chemistry, common sense, and internal motivation.
Investing is as much about understanding the human mind as it is about analysing numbers. Over the years, I have found that staying attuned to my emotional responses to market fluctuations has helped me better navigate t…
I found it interesting to show the contrast of someone who openly admits to constant mistakes without fearing it will harm their perceived competence with someone who strives to appear infallible.
What is an ETF? An ETF (Exchange-Traded Fund) lets you buy a whole stock index in a single share. Here is how I started investing in an index fund, how to choose one, and what to watch out for.
I test as INTJ, sometimes INTP. As a child I spent two months with only Lego. When advice is not logical, what I feel is not anger. It is closer to pain.
If I could go back to 2016, I would tell my younger self one thing: start investing immediately.
Investing 50% of My Income: Seven Years of Low-Cost Living in Prague.
2016 was a landmark year for me as I began one of the most beautiful periods of my life by entering my dream university.
When I first started using ChatGPT for SQL queries, I was blown away by how it transformed hours-long tasks into mere minutes of processing. However, This staggering efficiency brought an unexpected quandary. Did I still…
A personal ranking of 8 philosophy books that permanently changed my thinking, from Marcus Aurelius' Meditations to Heidegger's Being and Time. Why I have revisited some of them a hundred times.
Introvert vs extrovert: the real difference, from someone who lives it. The signs of an introvert, and how quiet became my most productive mode.
I listen carefully to the moderate and reflective, but I act with those with whom we agree on a common goal and are determined to achieve it.
To me, many commonly used signals and subtle indications feel like riddles. Therefore, I plead...
What is minimalism, and what does a minimalist lifestyle look like? For me it means few possessions, plain clothes, the same simple meals and a single focus. This is how minimalism became the core of my productivity.
A reflection on decision-making in marketing and advertising under uncertainty, risk and probability, and why good decisions should not be judged only by outcomes.
Yesterday, I had the opportunity to utilise so-called artificial intelligence to generate an SQL query, which would have otherwise required hours of manual effort. While it saved me a significant amount of time, it had a…
Head of Performance in e-commerce. I lead data-driven marketing, build BI systems, train AI agents, and apply phenomenology where analytics falls short. Based in Prague.
What is phenomenology? I studied it for three years at Charles University and still apply it every day, in marketing, investing, and AI. Most people dismiss it as too abstract.
Andrej Sámel warned about the breakup of Czechoslovakia and spoke out against Mečiar in the early 1990s. A personal and historical perspective on a turning point in Slovak history.
Something changed in the second year at university. However, there was no quick turnaround, it was a gradual change. Changing from “I am convinced that” through “I think that” to “I am thinking about”. It was a return to…
The protest at Letná is the biggest demonstration against the government since 1989's Velvet Revolution. Hundreds of thousands of people protest against the prime minister, but above all for justice and the rule of law.
A real pan-European political party? A single program, an individual membership, one financing and one headquarters? One might assume parties like that would make European Parliament (henceforth EP) elections simpler and…
Thousands of people protest for decent Slovakia one year after the murder of journalist Ján Kuciak.
What is the political situation in Slovakia right now? Which political parties are the most important ones? And what are the connections between them? In the diagram above you can see the current state of the party spect…
I promise to properly exercise the rights and fulfil the duties of a member of the academic community of Charles University.
I work in marketing. I studied politics and philosophy at Charles University in Prague, and philosophy changed how I see everything. I write about technology, finance, manipulation, and what it means to be human in a world that is changing faster than most people realise.
