Fantastic talk from @emitanaka.org on working with LLMs in #datascience at #ICOTS12. Highlights thinking of interacting with AI as a junior analyst with the statistician/data scientist in a manager/supervisor role to review/quality control output. Always enjoy hearing Emi talk! #statistics #teaching
