With every new technology, some jobs are lost while others are gained. People often focus on the former, but in this episode we chose to highlight the latter – a highly creative role that emerges alongside AI: the prompt engineer. Until AI can close the loop of its own, each tool still requires a set of prompts. Just like a composer feeds an instrument the notes to play, a prompt engineer feeds an AI a map of what to produce. And if we know anything from music it’s that composing great music takes great skill! In this episode we explore the emerging importance of prompting with Guy Parsons, the early learnings of how to do it effectively, and where this field might be going. Will the prompt engineer be more like the highly sought after DevOps engineer, or a proficiency like Excel that you find on every resume? Listen in to hear Guy’s take.
