“What concerns me most is not only that things like the Hugging Face incident can happen without our initially knowing about or understanding them — but how quickly they can happen.”
In this interview for The Harvard Gazette, Professor David J. Malan talks about the CS50 Duck, the changing landscape of AI, and the future of computer science education.

“It’s been fairly well-documented that even when you are not proactively revealing much about yourself, your devices are, your browsers are, your behaviors are, so typically by nature of what you’re clicking on, what sites you’re visiting, how long you’re spending on them, social media companies can create a profile about you… because they’re detecting patterns in those behaviours of yours.”
Professor David J. Malan goes on ABC’s Radio National Breakfast to talk about the nature of social media algorithms and what their regulation could look like.
