• Nvidia is planning to invest up to $100 billion in OpenAI. (Tom's Hardware)
  
  So that OpenAI can spend the money on 10 gigawatts worth of Nvidia hardware.
  
  It's not a bubble.
  
  It's a Ponzi scheme with extra steps.*

• A Twitch streamer (I know) who was raising money for his cancer treatments with blockchain donations (I know) lost everything he had raised in minutes after installing a Steam game called BlockBlasters recommended to him in a chat message (I know). (Decrypt.co)
  
  Most of this is legitimate. Streamer "RastalandTV" does have stage 4 cancer, has been raising funds through blockchain donations, and BlockBlasters was compromised at the end of August and has stolen at least $150,000 in crypto funds from victims. It has since been pulled from Steam.
  
  Happy ending time: Crypto bro Alex Becker - I hope he'll forgive me for calling him that - not only stepped in to cover the loss, but stepped in twice because the first donation he made was also lost.
  
  Not so happy ending time: Blockchains.
  
  
  
• Mathematicians who have spent 150 years working on a simple way to categorise the complexity of knots have come to a stunning conclusion: We have no idea. (Quanta)
  
  None whatsoever:

  But from another perspective, that only makes the unknotting number more intriguing. "There's just much more complexity and unknowns about knot theory than we knew there were a few months ago," Livingston said.

  You might even say it's a knotty problem.
  
  What's more, we don't know why we don't know what we don't know. We just know we don't know it:

  "I'm still stymied by this most basic question" about the unknotting number, Moore said. "That just lights the fire under you."

  Have you checked the answers at the end of the book?
  
  
  
• Have you already scratched your hugely expensive iPhone 17 Pro Max. Yes. Yes you have. (The Verge)
  
  Meanwhile my $120 Moto G14 is in pristine condition.
