The Rules Nobody Wrote Down

AI can learn how your business usually works. The harder question is which of those habits deserve to become rules.

AI makes it increasingly easy to observe how a business works, learn from previous decisions and repeat them. That sounds ideal until you remember what history actually contains: exceptions, temporary workarounds, personal judgement and mistakes, sitting alongside actual policy and indistinguishable from it. The more capable agents become, the more it matters to separate what happened before from what the company has decided should happen again.

When Everyone Does Build

Part two of 'When Everyone Can Build': the month the flood arrived, in data. Cheaper builds, many more of them, and a bill that moved to where dashboards don't look.

AI Can Now Execute the Wrong Idea for Much Longer

The Drag-and-Drop Illusion

Drop a hundred files into an AI, or point it at the whole web, and the answer arrives in seconds, wearing a citation. Whether it deserves belief is decided by a chain of steps you never see.

About

Not automated opinions. Accelerated judgement.

I'm Johnny Han — once an IT consultant at IBM, now a Principal AI Architect. This is my personal press: a place to turn messy strategic thoughts into polished, shareable arguments. I use AI as a production engine; the opinion, framing and final taste are mine.

How it's built

AI helps structure, draft, and gather research. The legwork is automated; the perspective is not.

The Filter

Every piece is shaped, edited, and approved by me to ensure the judgement is mine.

The Promise

Nothing is published unless I would defend the judgement behind it in front of smart, critical people.
