Machines Like Us S1E19 — A Computer Scientist Answers Your Questions About AI

Jan. 28, 2025

We’ve spent a lot of time on this show talking about AI: how it’s changing war, how your doctor might be using it, and whether or not chatbots are curing, or exacerbating, loneliness.

But what we haven’t done on this show is try to explain how AI actually works. So this seemed like as good a time as any to ask our listeners if they had any burning questions about AI. And it turns out you did.

Where do our queries go once they’ve been fed into ChatGPT? What are the justifications for using a chatbot that may have been trained on plagiarized material? And why do we even need AI in the first place?

To help answer your questions, we are joined by Derek Ruths, a Professor of Computer Science at McGill University, and the best person I know at helping people (including myself) understand artificial intelligence.
