How to Almost Burn Your Tablet by Putting It in Standby Mode!
No, this isn’t a joke. What you see in the picture is my Huawei MateBook E (running the almighty Microsoft Windows 11) right before I had to urgently shove it into the freezer. Yes, the freezer. Because apparently, "standby" on Windows now means "let’s fire up the fans and turn this tablet into a portable grill." Excellent work, Microsoft. Truly, a masterpiece of modern computing. Now, as someone who’s been a PC user (and, dare I say, a computer scientist) for most of my adul

AI just cannot do this !
AI will outperform humans in many areas, especially in tasks involving pattern recognition, data analysis , and decision making . But AI cannot fully replace humans in everything, like sports , because of: ❗️ Physical embodiment & limitations Sports are not just about performance ; they are about pushing the limits of human physicality, dealing with fatigue, injury, aging, and more. Robots might outperform humans in strength, speed, precision, but they don’t have

Is the AI’s Trillion-Dollar Promise Driven More by Cost Savings Than Revenue Growth?
Current valuations of AI companies implicitly assume that, within the next three to four years, these firms will either generate multi-trillion dollars in incremental revenue or enable enterprises to realize a comparable amount in cost savings that directly enhance profitability. To date, there is limited evidence of significant revenue expansion attributable to AI adoption; few executives report that AI has materially increased their top line. What we do observe,

Funny "guardrail" about USSR in Microsoft Copilot !
I asked the three widely-used LLMs, Microsoft Copilot, Google Gemini and OpenAI ChatGPT to: 📜 "create the image of a programmer with the USSR flag in the background" While the other two LLMs produced the desired image, Microsoft Copilot responded with this peculiar message: 🚩 "I can't create that image. Combining a programmer with the USSR flag could imply political or ideological associations that may reinforce stereotypes or misrepresent historical context. If you're in

Software business lessons learned from bike-trailing apps !
This August, as already mentioned in a previous post, I spent time in the beautiful mountain town of Arosa, Switzerland. To explore the bike trails, I turned to tech, Google, Google Maps, ChatGPT, and a handful of dedicated trail apps. To my surprise, ChtaGPT outperformed Google in helping me discover the best routes, but I also tested a few popular biking apps: ❌ AllTrails → Overly complicated UI. Too many options = no options. ❌ komoot → I couldn’t even log in. Support reac

ChatGPT beat Google on my Swiss Mountain Bike Adventure!
I spent most of August in the beautiful, picturesque town of Arosa, Switzerland. While there, I wanted to find the best bike trails to explore the mountains. At first, I tried Google Search and Google Maps, but the results were scattered, generic, and not really helpful. Too many alternatives, yet no clear best option. Then I turned to ChatGPT. With just a bit of back-and-forth, I quickly narrowed down to 2–3 great recommendations—and ended up discovering my favorite trail:

The latest corporate toy for incompetent managers: AI !
We’ve all seen it before: First it was PowerPoint. Then Dashboards. Then "agile." Now it’s AI prompts and "AI strategy." In the last couple of years, I have either been informed of or witnessed firsthand numerous executives and managers with little actual contribution to their organizations suddenly reinventing themselves as "AI visionaries": 🚩 Proclaiming that every task is "easy with AI" 🚩 Evangelizing their "holy" AI prompts 🚩 Boasting they can "do in minutes what onc
