"Instructors are finished."

because AI itself is the greatest teacher now, so learners no longer need a human guide.

My first reaction was the comfortable one: plenty of people still find even basic digital tools unfamiliar, so there will be work for us for a long time.

Then I spent seven days on a vibe coding project. AI introduction, use cases, task design, implementation, development, testing — five days is enough to cover all of it. Past that point, there isn't much left for an instructor to do.

What I noticed during those days:

• The instructor asks AI for advice. So do the students.
• The one thing left for the instructor — sharing what you experienced first — students can now build that experience themselves, with AI beside them.
• And since AI does the making and the working itself — Office documents, computer tasks, and before long even physical machines — "I've done this before" has lost its value too.

Years ago, I was disappointed watching developers turn their knowledge into castles, walled off so no one could come near, because that was how they made a living. Knowledge didn't get shared. Somewhere along the way, knowledge became a public good.

I don't think this takes a generation. In a year or two, this public good will come built in — for everyone, by default.

Which leaves a question I keep turning over:

In a world where knowledge — and the work done with it — can no longer be a weapon or a product, what can people still sell to one another?
