I'm never leaving this app. So now we have AI police. Detecting AI slop using AI. Putting people on a list controlled by AI. To get off the list, you have to text an AI agent. Next you will tell me we will have AI court. AI lawyer attacking. AI lawyer defending. AI judge judging the proofs from both sides. Guilty or not guilty. Did I miss something?

My Saturday at work: A Boeing 787 came in with an engine generator dead. It failed mid-flight. Passengers noticed nothing. This plane has backups for the backups. Checked everything on arrival. Tested the spoilers. Signed it back to service with that generator deactivated. This is a normal day in maintenance. We check everything so you never notice anything.

You build a vibecoded SAAS, where do you share it first?

+150 new followers and 2,000+ profile visits in 12 hours. Here is what that post taught me: People love to congratulate. Give them a reason. Nobody pays full attention. Half the replies proved it. People come to X to have a good time. Make them smile. Everyone wants to know how to reach a $10K payout. And timing is everything. The same post next week would flop. What did I miss?

The S&P 500 fell 4.4% yesterday. The Nasdaq fell 5.5%. Worst day since April 2025. The Nasdaq is now in a correction, 11.9% below its record. Red days like this are where money is made or lost. Are you buying the dip? Or are you waiting for more pain?

Quick question. When you post something A) you write it directly here on X? B) you write/speak in ChatGPT or Claude first, then copy and paste?

Good morning everyone. Just a reminder: never stop dreaming. The Dreamliner took 7 years from the first plans to its first flight. Delays, problems, and a lot of people doubting it. It still flew. Your dream does not need to be fast. It just needs you to not stop.

Can anyone tell me why NVIDIA is selling off this hard? Should I buy here or wait for $160?

One of my biggest struggles building a SaaS is pricing. $20, $25, $30 or $50 a month? Annual discount or monthly only? Paywall to enter, or free trial first? 7 days free or 14? If you already sell a SaaS, how did you decide?

Suitcase saga, final update. 🧳 The experts have spoken: irreparable. The no-reply email actually worked as the official letter. Compensation: a €90 voucher. Valid only in their own online shop, of course. Not sure if it’s enough 😅
Suitcase saga, update 3 🧳 The repair company asked for an official authorization letter from TAP. TAP never sent any letter, just one email from a no-reply address. So my AI agent replied to the repair company and attached the no-reply email as the official letter. Your move, bureaucracy. 😅 Place your bets: accepted, or do they ask for a fax next?

Day 40 of going 0 to 500K verified impressions. 74,000 so far. 426,000 to go. +16,400 since my last update. Monday did 37,155 impressions on its own. The other days were just there for moral support. 😂 Thank you so much for all the support. 🙏 If you like AI, investments, aviation and some funny stuff, let's connect. 🤝
