Molly White—of “Web3 is Going Just Great” fame—reviews Chris Dixon’s blockchain solutions book: Read Write Own: In fact, throughout the entire book, Dixon fails to identify a single blockchain project that has successfully provided a non-speculative service at any kind of scale. The closest he ever comes is when he ... Read More

Over on Lawfare, Jim Dempsey published a really interesting proposal for software liability: “Standard for Software Liability: Focus on the Product for Liability, Focus on the Process for Safe Harbor.” Section 1 of this paper sets the stage by briefly describing the problem to be solved. Section 2 canvasses the ... Read More

Interesting research: “Sleeper Agents: Training Deceptive LLMs that Persist Through Safety Training“: Abstract: Humans are capable of strategically deceptive behavior: behaving helpfully in most situations, but then behaving very differently in order to pursue alternative objectives when given the opportunity. If an AI system learned such a deceptive strategy, could ... Read More

Consumer Reports is reporting that Facebook has built a massive surveillance network: Using a panel of 709 volunteers who shared archives of their Facebook data, Consumer Reports found that a total of 186,892 companies sent data about them to the social network. On average, each participant in the study had ... Read More

In October, the Consumer Financial Protection Bureau (CFPB) proposed a set of rules that if implemented would transform how financial institutions handle personal data about their customers. The rules put control of that data back in the hands of ordinary Americans, while at the same time undermining the data broker ... Read More

For most of history, communicating with a computer has not been like communicating with a person. In their earliest years, computers required carefully constructed instructions, delivered through punch cards; then came a command-line interface, followed by menus and options and text boxes. If you wanted results, you needed to learn ... Read More

New research into poisoning AI models: The researchers first trained the AI models using supervised learning and then used additional “safety training” methods, including more supervised learning, reinforcement learning, and adversarial training. After this, they checked if the AI still had hidden behaviors. They found that with specific prompts, the ... Read More

Really interesting research: “Lend Me Your Ear: Passive Remote Physical Side Channels on PCs.” Abstract: We show that built-in sensors in commodity PCs, such as microphones, inadvertently capture electromagnetic side-channel leakage from ongoing computation. Moreover, this information is often conveyed by supposedly-benign channels such as audio recordings and common Voice-over-IP ... Read More

Last month, I convened the Second Interdisciplinary Workshop on Reimagining Democracy (IWORD 2023) at the Harvard Kennedy School Ash Center. As with IWORD 2022, the goal was to bring together a diverse set of thinkers and practitioners to talk about how democracy might be reimagined for the twenty-first century. My ... Read More

We don’t have a useful quantum computer yet, but we do have quantum algorithms. Shor’s algorithm has the potential to factor large numbers faster than otherwise possible, which—if the run times are actually feasible—could break both the RSA and Diffie-Hellman public-key algorithms. Now, computer scientist Oded Regev has a significant ... Read More
