You know how to write prompts that get results. This will only get you so far. Using an LLM for one-off tasks is like putting a Formula 1 […]

Last week, I told you to get off the melting iceberg. The repetitive, rule-based work of the Operator quadrant in my Human-AI Career Nexus is being automated. This is not a threat.

This week, let’s turn theory into practice by uncovering how inferential statistics are applied in real-world scenarios — and the limitations analysts must navigate when using them. Inferential statistics enable us to go beyond the immediate data […]
