AI is the new Printing Press (another trite take)

A personal essay comparing AI to the printing press, arguing that AI did not invent token generation but made it radically more efficient. The author uses an aerodynamics analogy to explain how AI approximates intelligence through scaling, and predicts that AI may have a biological impact on the human brain similar to language.

  • AI, like the printing press, accelerates information propagation without inventing the underlying good.

Would AI have ruined my 100 days of algorithms?

Eight years ago, the author started a '100 Days of Algorithms' challenge, handcrafting code to learn algorithms. Now, with a review by GPT-5.6 revealing many flaws—like incomplete max flow, buggy graph algorithms, and broken BST implementations—he reflects on whether AI would have helped or hindered his learning. He decides to preserve the code as a historical artifact and update the README honestly.

  • The author's 100-day challenge stretched over eight years, with hand-coded algorithms.
  • GPT-5.6 code review identified numerous defects: max flow stub, BFS acting depth-first, broken BST, etc.

The One-Step Trap (In AI Research)

The one-step trap is a common mistake in AI research where researchers assume that learned predictions can be mostly one-step, with longer-term predictions generated by iterating them. While appealing, this approach suffers from error accumulation and exponential computational complexity, making it impractical. Rich Sutton argues for temporally abstract models using options and GVFs as a solution.

  • Iterating imperfect one-step predictions causes errors to compound, leading to poor long-term predictions.
  • Computational complexity grows exponentially with prediction horizon in stochastic settings.

Apple’s failed self-driving car program left a legacy of powerful AI chips

Apple's self-driving car program never really got off the ground, but it may have been what made the company's chips the powerful AI performers they are. Early in the development of the self-driving platform, Apple realized that it would need powerful on-device AI processing. While the car processor was never finished, as Mark Gurman details in his latest Power On newsletter, it did lead to the development of the Neural Engine, the backbone of Apple's on-device AI processing. The Neural Engine made its debut with the iPhone X and the A11 Bionic. In those early days, it was primarily used for computer vision, powering FaceID, Animoji, and a … Read the full story at The Verge.

  • Apple's car project spurred creation of Neural Engine, now core to on-device AI.

6 months to live for open models

Open-source AI faces its most serious viability test. White House discussions on executive orders to restrict open models, plus policy debates on distillation and frontier capabilities, could lead to a ban on advanced open-weight models within 6 months.
