Veritasium is one of the oldest and consistently greatest science channels

you can open the freaking Control Center using keyboard?! Notification Center using keyboard?! Fn rules

Tried it, got frustrated, never used it since

Reminds me of “Children of Time” by Adrian Tchaikovsky that I am reading now

I wish the OP added “Justin-27” and “TheJosh” to the picture

Ah, I am being thick) thanks!

I like this guy)

Elaborate!

Gotta keep it cool

Asking for a friend, of course

Classy

I wonder what they thought of when they wrote “Security Team.” I just think of security guards.

Thanks! TIL =)

Now that I think of it, it seems to be at the core of some issues with training AI agents using reinforcement learning (e.g., if you choose a wrong metric, you’d get the behavior that makes sense for the agent but not what you want) and with any kind of planned economy (you need targets for planning, but people manipulate them, so you do not get what you want)

Thanks for uncovering this report, very insightful and lots of great examples!

Could anyone explain what a “test coverage” means?

Still, an interesting take, same terms mean different things to different people

That’s what’s happening with Google and Instagram search algorithms. People figure out how to manipulate them and start spamming. Then the search results deteriorate and you have to modify the algorithm.

Thanks, yes, I saw that one, too, but I liked the emphasis on relationships. The shorter version is easier to get but it does not explain why this happens. E.g., you can observe some relationship (e.g., test results and a student’s intelligence) and then you target grades. But then you have an incentive to teach to the test, which breaks down the relationship between test results and intelligence. Other people here gave great examples of relationships that can fail.

I like the bones and skull graphic, makes it so much more ominous
