Ask HN: What's the best lecture or talk you've seen in 2025?

I liked this one. Even though it's older I did see in 2025 myself. Does that count?

I mean it's probably nothing useful for most people here but I was impressed by CS50x. I wish everyone everyone had access to quality teachers that are as competent/articulate/put together/etc as the guy who teaches CS50 (for all subjects.)
