The job did not get replaced.
You already forecast. What can be true in a year or two, what has to start this quarter, which dependency is fake. AI changed the object of that forecast: what a prototype costs, how a model fails, what gets cheap before the roadmap does.
In practice, if you have not watched a model assign probability to the next token, or seen a 4-bit quant miss a logic question with full confidence, you are calling those shots from a brochure. The certificate does not fix that.
A scale I actually use.
Five levels. A little overwrought. Roughly what I see after an “AI rollout.” Judge them by what this person’s work changes for other people, not by how clever the prompts look. Most people who finished the training are still at 1.
-
Assisted
Same workflow. Drafts come back faster. Summaries, rewrites, notes. This is where the course ends.
-
Fluent
You pick the model on purpose and you build the context instead of dumping the ticket into the box. You are faster. The org is not.
-
Builder
You leave the meeting with something running. A prototype, a pipeline, an eval set. Engineering can argue with that instead of a slide.
-
Orchestrator
Someone else can install what you made. Until then it is personal productivity with better tools.
-
Multiplier
Discovery and ship criteria assume a prototype is cheap. The way of working still holds if you leave.
Most buildings are a pile of 1s, a few 3s, and no 5s. Four and five are usually a permission problem. Someone with authority has to let a PM build.
Before a customer sees it.
Speeding up go-to-market only counts if you can still answer these. If a team cannot fail the test, it is not a test.
-
Grounding
If the answer has no source, it does not go to someone whose decision costs money.
-
Data
You can name which data hits which model, under what agreement. “It’s just a prompt” is how data leaves the building.
-
Owner
A named person owns the output that reaches a customer. No name, no ship.
-
Measurement
A baseline, and a number that could prove you were wrong. Enthusiasm does not count.
The book and the labs.
I wrote the book so the chapters were not just claims. The labs are how you check.
Latent Space
A Product Manager’s Guide to How AI Actually Works. Live on Amazon.
Space, generation, architecture, modification, and how to read a capability curve so the roadmap is not a wish.
Six labs
Unzip, double-click RUN-THIS-Windows.bat, start with embeddings. About forty minutes. You do not need GitHub.
CURRENT.md is the only file that is allowed to go stale. If a command fails, start there.
