What the world needs isn't "Artificial Intelligence" but Optimized Computational Methodologies

Top Carbon Chauvinist • 79 implied HN points • 21 Jun 24
🕹 Technology Artificial Intelligence Machine Learning Engineering Mathematics
  1. We should focus on making smarter tools instead of trying to make machines think like humans. Real progress comes from solving practical problems, not imitating nature.
  2. Copying how living things work is often a bad approach. Nature is full of flaws, and we don't need to mimic those to create better designs.
  3. It's important to clearly define the problems we want machines to solve. Without a clear goal, projects will struggle and waste resources on unnecessary tasks.

Notes on Google's Attempt at Self-Disruption

Brad DeLong's Grasping Reality • 292 implied HN points • 30 Jul 25
🕹 Technology AI Search Innovation Business Model Digital marketing
  1. Google is changing how it operates by using AI to summarize search results instead of just linking users to websites. This could reduce traffic to publishers who rely on clicks from Google.
  2. While fewer people might click on links due to AI summaries, Google claims that the advertisers are still willing to pay more for the remaining clicks, suggesting a shift in user intent and engagement.
  3. This big move to AI could be risky. If it works out, Google might dominate future online searches, but if it fails, they could end up with a lot of costly infrastructure without much to show for it.

Deep Research, information vs. insight, and the nature of science

Democratizing Automation • 775 implied HN points • 12 Feb 25
🕹 Technology AI Science Research Innovation Computing
  1. AI will change how scientists work by speeding up research and helping with complex math and coding. This means scientists will need to ask the right questions to get the most out of these tools.
  2. While AI can process a lot of information quickly, it can't create real insights or make new discoveries on its own. It works best when used to make existing scientific progress faster.
  3. The rise of AI in science may change traditional practices and institutions. We need to rethink how research is done, especially how quickly new knowledge is produced compared to how long it takes to review that knowledge.

($) H20 and the Broken Export Control Debate

Interconnected • 293 implied HN points • 29 Jul 25
🕹 Technology AI Export Controls Chinese Tech Chips Policy
  1. The export control debate about Nvidia's H20 chip is complicated because both sides use the same evidence to argue their points. It shows that the argument is not fully addressing the real concerns.
  2. Chinese tech companies are placing large orders for these H20 chips, but they fear getting too reliant on Nvidia's products instead of developing their own. This means they want to ensure they have various options.
  3. Interestingly, many Chinese companies also dislike Huawei, as they don’t want to be stuck with a single supplier. They are looking for better choices in the tech landscape.
