Hedge 312: Keys and DNS

The entire technology world has, for decades, treated the IP address as a shorthand host identifier. This is clearly not the way IP was designed, but what are our other choices? In this episode of the Hedge, Scott Robohn joins Russ And Tom to discuss a recent paper arguing cryptographic keys should be the primary host identifier, and another article on the centrality of DNS to the Internet.

AI assistants now hand you a single, ready-made answer, and a harder question comes with it: who decides what we get to know, and what never makes it into the reply?

 


Vendors are trying to position “confidential computing” as the technical backbone of Europe’s sovereign cloud ambitions. But new research shows that a security protocol used to prove cryptographic trust in the system may have a fundamental architectural flaw.

 


The Internet should stop asking only who was in the room. It should ask who can bind the party bearing the loss.

 


America won’t beat China by banning AI. We’ll win by building the world’s best open models and letting innovation—not government—lead the way.

Differential privacy (DP) data synthesizers are increasingly proposed to afford public release of sensitive information, offering theoretical guarantees for privacy (and, in some cases, utility), but limited empirical evidence of utility in practical settings.

 


LLMs are relentless data miners that train on unimaginably large text databases, looking for multi-dimensional statistical relationships among small chunks of text called tokens.

Hedge 311: The Dangers of AI

We are often told that if engineers who don’t go “all in” on AI will be left behind. While there are a few voices who argue that AI can be a dangerous tool, impacting not only the quality of our work, but the very quality of our thinking skills. Doug Smith, a critic of using AI for engineering, joins this episode of the Hedge to argue the contrary view of AI.

What are the dangers of relying on AI?

It’s no longer just about your IP address or the specific endpoint you think you’re connecting to, it’s about your location and which intermediary services can most effectively handle your request.

 


Earlier this month, a German court ruled that Google is liable for its AI search summaries. Rejecting defenses like “users can check for themselves,” and that they generally know “that information generated with AI should not be blindly trusted,” the court held that the AI’s summaries are reflections of the company and “above all an expression of Google’s business activities.”
