Notes on AI, trust, and how people really learn to use it.

I'm Beza Lefebo. This is my personal space for thinking out loud about artificial intelligence: why responsible AI has to be shown rather than claimed, why most AI awareness training leaves work unchanged, and what learning AI role by role could look like instead. Everything here is my own view, shared to start conversations, not to sell anything.

The idea behind most of my writing

“The organization has a completion rate. It does not have a capability.”

In a field experiment with 758 consultants, AI raised the quality of work on tasks inside its capability by about 40 percent, and cut correct answers by 19 percentage points on a task just outside it. Researchers call this the jagged frontier.

If AI's usefulness changes task by task, a single all-staff course cannot tell a budget analyst, a program manager, and an auditor where the line falls in their own work. That gap is what I study.
