AI is changing how organizations operate but the leaders who create the most value won't be the ones who automate everything. They'll be the ones who know where human judgment matters most. Join me on June 25 for a free global keynote with Udemy, where we'll explore: - The decisions leaders should never fully automate - Why human judgment becomes more important as AI capabilities expand - Common pitfalls when organizations over-rely on AI systems - Practical frameworks for responsible AI adoption Looking forward to the conversation.

“The LLM decided” is not an explanation. It's a gap where an explanation should be. Every automated outcome has a human lineage: someone chose the objective, set the constraints, and signed off on deployment. The accountability didn't disappear. It just got buried deep enough that nobody has to feel it until something goes wrong. And when something goes wrong at scale, feeling it is no longer optional. This is the part of the AI conversation that keeps getting skipped. #DecisionIntelligence #AILeadership #Governance #ExecutiveLeadership

These so called "AI layoffs" are most likely to happen at companies who are doing the least AI. 🧐 Here's my deep dive: Who's on team Medium? bit.ly/4g0zJzb Who's on team Substack? bit.ly/quaesita_layoffs

AI sees what you did, not why you did it. It captures patterns in behavior, not the intent behind decisions. When organizations treat data exhaust as meaning, responsibility slips away. Patterns are useful. Purpose still belongs to humans. We’ll talk about this in the latest cohort of Decision-Making with ChatGPT. Live Q&A is from 8 AM to 10 AM ET on Monday, June 8th. Don’t miss it! decisiongptcourse.com #DecisionIntelligence #AILeadership #AppliedAI #RiskManagement

Last year, 4.5% of US layoffs were "due to AI" and now this year in March, it's 25%. In April, the number is 26%.* I smell a rat. 🐀 🐀 🐀 🐀 🐀 🐀 🐀 🐀 🐀 🐀 🐀 Here's my take on what's happening: bit.ly/quaesita_layoffs If you find it useful, please share it with someone who needs to see it. Let's prevent a big mistake. Separately, my Decision-Making with ChatGPT course is running on-demand with a 2h live Q&A session with me on Monday.

Anyone else grew up playing the Mech Warrior video games? China has just made your fantasy a reality.
Unitree GD01 is the world's first production-ready manned transformable mecha. It is 9 feet tall, 500 kilograms and can walk, crawl and break cinderblock walls. It was announced by Unitree Robotics on May 12, 2026. It is a civilian vehicle that a human pilot rides inside (open cockpit in the torso) and not yet a fully autonomous robot. It transforms between bipedal (upright 2-leg walking) and quadrupedal (4-leg crawling) modes for different terrain. It costs $650,000. @elonmusk @SawyerMerritt @herbertong @roydendsouza

"Some might believe that matters of AI are best handled by computer scientists like myself. They are mistaken: the questions raised by AI are bigger than the AI research community, not just in their implications, but also in their nature. AI systems are not engineered the way a bridge or an airplane is engineered. We understand an airplane because we designed every part of it and we understand the physics that act on it. AI models are not like that. They are grown, on a structure roughly modeled after the brain, on an enormous inheritance of human thought and speech."

💣 AI use cases are a trap. AI helps you answer: How do I make this happen? But it’s still leadership's that much answer: Should this exist at all? Speed amplifies direction; it doesn’t choose it. As automation becomes easier, judgment and being intentional becomes more valuable. That distinction scales up when we make complex systems so much easier to scale. Which brings me to one of the biggest traps I'm seeing these days: every leader is asking for advice on AI use cases. But today, more than ever, seeing AI use cases is bad for you. Copying someone else's AI playbook will hurt you. What you need is to know how to make your own AI playbook. Agree? Disagree? Want to fight me? Tomorrow's your chance! I'll get into it, live, tomorrow on two platforms: LinkedIn Premium subscribers, you can tell me live here on LinkedIn on May 1 at 12 PM ET for How to Customize Agentic AI for Your Organization: lnkd.in/etwn8UDJ And if you’re in the mood for a course, the live Q&A for the latest cohort of Decision-Making with ChatGPT comes right after at 1:30 PM ET: decisiongptcourse.com Come curious. #DecisionIntelligence #AILeadership #ExecutiveLeadership #RiskManagement
