The AI Efficiency Trap: Why Firing Your Team Won’t Get You to 100x

Most companies are looking at AI through the wrong end of the telescope. They see tools like Claude or ChatGPT and think, “Great, I can fire half my engineers, cut my R&D budget, and build the exact same product for pennies.” This is a defensive, race-to-the-bottom mindset. If you are only using AI to shrink…

The Neuroscience of Creative Genius: Balancing Brilliance and Madness

The “Mad Genius” Paradox History has long suggested a link between madness and genius. Modern neuroscience suggests that creative geniuses may indeed possess the “right amount” of crazy. The key predictor of high creative achievement appears to be a specific cognitive combination: Reduced Latent Inhibition (a difficulty in filtering out irrelevant stimuli) paired with High IQ. In this…

Elon Musk: The Converging Tech Tree

This was one of the most useful videos I’ve seen this year. Below is the summary of some of the highlights from the video. 1. Methodology: Problem Solving & Business Creation The “Limiting Factor” Approach Musk’s primary algorithm for business and engineering is identifying and attacking the single biggest constraint holding back progress. Maniacal Urgency…

The Infinity Game

Human civilization has always been engaged in a single, desperate pursuit: the flight from our greatest fear. It is not fear of the unknown, but fear of the ending. The fear of finiteness. Mortality. The terrified realization that things run out. For millennia, we have expressed this anxietyβ€”and our yearning for the oppositeβ€”through religion. Whether…

Vibe Coding

I’ve spent the past week living in Claude Code and Codex. Being a daily ChatGPT user alone won’t get you a true sense of what AI can already do today. Using these vibe coding platforms builds a far more direct intuition for what AI can actually achieve right now. It’s incredible how this reshapes the…

The Long Arc of Tenacity: Nancy Wexler’s Journey

Most people underestimate time. We think of effort as something you can measure in hours, days, maybe a few years at best. We live in startup timeβ€”sprints, ship cycles, quarterly OKRs. But there’s another kind of time, one that runs on decades. That’s the time Nancy Wexler lived in. Wexler’s story begins not in a…

My Life’s Priorities

I read this quote a long time ago and it has stayed with me ever since: β€œSomeone once told me the definition of Hell: The last day you have on earth, the person you became will meet the person you could have become.” – Anonymous This idea sparked my lifelong pursuit of unlocking not only…

Foundations of the A2A Economy: AI Agent Interoperability Protocols

With the rise of Anthropic’s MCP (& quickly becoming one of the emerging open standards) and Google’s recent announcement of the Agent2Agent Protocol (A2A), it’s clear the technology world is racing full-speed toward laying the foundations of the A2A economy. What I initially thought would take years is now unfolding in mere months β€” a…

AI-Default Organizations

Tobi LΓΌtke recently shared Shopify’s internal memo setting the baseline expectation for AI usage across their company. If you think back a few decades, organizations began expecting employees to use desktop computers by default. Then it was Microsoft Office. Then it was the internet. Employees who adopted these tools early were seen as far more…

Evolutionary Prompting: Using modular prompts to improve AI agent performance

There’s a lot to be said about efficiencyβ€”whether you’re writing code or crafting prompts for an AI. The basic idea is simple: if you can break something complicated into reusable, modifiable parts, you can build better systems faster. In AI, that means rethinking how we write prompts for LLMs and AI agents. Modular Prompts: The…

The Three Stages of the A2A Economy

In just a few years, AIβ€”specifically OpenAIβ€”has transformed what was once an interesting toy into a force that’s reshaping various industries and jobs in a non-linear way. Enter the new economic paradigm, known as the agent-to-agent (A2A) economy, where AI-driven agents from different organizationsβ€”or even between businesses and consumersβ€”collaborate, negotiate, and transact autonomously. At the…

Rise of the A2A economy: How AI agent-to-agent interactions will reshape the world

At Sendbird, we’ve been actively working with companies across the globe that are considering the adoption of conversational AI to enhance their customer service. During this process, we’ve encountered many forward-looking enterprises eager to accelerate their adoption of AI agentsβ€”not just for customer service, but also to drive transactions and revenue growth. This got us…

Annual Operating Rhythms and Time Budgeting

As I progressed through life, I became increasingly aware of two major constraints on productivity: time and energy. While energy depends on the health of both body and mind, today I’ll focus on time. By the time you’re 10–20 years into your career, you (hopefully) have a solid grasp of managing your schedule. I recommend…

My Camera Bag Setup (FujiFilm X100VI)

Last update: 2025-01-01 Perfect camera bag setup didn’t exi… I quietly enjoy capturing photos of the people I meet, the places I visit, and the things that inspire meβ€”like architecture, engineering, and art. To simplify traveling and avoid the complexity of lugging around a full camera kit, I’ve switched to using compact fixed-lens cameras. The…
