A one-minute clip from The Simpsons in which Lisa demonstrates the Anti-Tiger Rock to Homer, showing that the rock keeps away tigers because no tigers are around. It is a short comedic scene about faulty causal reasoning.

HN commenters post it as a joke whenever a thread involves correlation, causation, or unfalsifiable protective measures.

Crime's been descending from the COVID blip for a while, everywhere, Flock or otherwise. My city saw zero murders in Q1; 2021 saw ~15 by now. In other words: ▶ this video

Such claims of protection, reminds me of this Simpsons episode: ▶ this video It's true that the COVID-19 initial variants were very dangerous, and that the vaccines worked against these variants. However, the virus in 2024 is different from the one in 2019, but the side-effects, you are "guaranteed" to pay them. You really have to think twice.

The issue is how do you provide the evidence for that. In other terms, how do you differentiate your effect from that of Homer Simpson's Bear Patrol and Lisa's tiger-repellant rock [0]? [0] ▶ this video

And here is a clip of the relevant scene, from the episode "Much Apu About Nothing" (1996), ▶ this video Quoting from its IMDB entry at link : Lisa : Dad, what if I were to tell you that this rock keeps away tigers. Homer : Uh-huh, and how does it work? Lisa : It doesn't work. It's just a stupid rock. Homer : I see. Lisa : But you don't see any tigers around, do you? Homer : Lisa, I'd like to buy your rock.

Lisa Simpson has a rock she would like to sell you: ▶ this video I mean, yeah, I get it. I worry about general purpose computing going away too. I remember Stallman and Doctorow talking about this in the early 2000s and saw many iterations of this same thread pop up on Slashdot, HN, Digg, Reddit, etc. over the years. I dunno man, I guess I’m just skeptical over the dooming at this point. I think a bigger issue is less about whether we will be able to run whatever we want on our computer, and more that the internet has just become a cesspool of ads, clickbait, ragebait, and app sandboxed content that’s not discoverable by search engines. I think you’ll always have a fairly reasonable choice of computers to run whatever software you want on. But todays internet just isn’t very fun anymore.
