There’s good reason to fear that A.I. systems like ChatGPT and GPT4 will harm democracy. Public debate may be overwhelmed by industrial quantities of autogenerated argument. People might fall down political rabbit holes, taken in by superficially convincing bullshit, or obsessed by folies à deux relationships with machine personalities that don’t really exist.

These risks may be the fallout of a world where businesses deploy poorly tested A.I. systems in a battle for market share, each hoping to establish a monopoly.

But dystopia isn’t the only possible future. A.I. could advance the public good, not private profit, and bolster democracy instead of undermining it. That would require an A.I. not under the control of a large tech monopoly, but rather developed by government and available to all citizens. This public option is within reach if we want it…

Brace Yourself for a Tidal Wave of ChatGPT Email Scams

Thanks to large language models, a single scammer can run hundreds or thousands of cons in parallel, night and day, in every language under the sun.

Here’s an experiment being run by undergraduate computer science students everywhere: Ask ChatGPT to generate phishing emails, and test whether these are better at persuading victims to respond or click on the link than the usual spam. It’s an interesting experiment, and the results are likely to vary wildly based on the details of the experiment.

But while it’s an easy experiment to run, it misses the real risk of large language models (LLMs) writing scam emails. Today’s human-run scams aren’t limited by the number of people who respond to the initial email contact. They’re limited by the labor-intensive process of persuading those people to send the scammer money. LLMs are about to change that. A decade ago, one type of spam email had become a punchline on every late-night show: “I am the son of the late king of Nigeria in need of your assistance …” Nearly everyone had gotten one or a thousand of those emails, to the point that it seemed everyone must have known they were scams…

How AI Could Write Our Laws

ChatGPT and other AIs could supercharge the influence of lobbyists—but only if we let them

Nearly 90% of the multibillion-dollar federal lobbying apparatus in the United States serves corporate interests. In some cases, the objective of that money is obvious. Google pours millions into lobbying on bills related to antitrust regulation. Big energy companies expect action whenever there is a move to end drilling leases for federal lands, in exchange for the tens of millions they contribute to congressional reelection campaigns.

But lobbying strategies are not always so blunt, and the interests involved are not always so obvious. Consider, for example, a 2013 …

A Hacker’s Mind: How the Powerful Bend Society’s Rules, and How to Bend Them Back

Bruce Schneier is a Lecturer in Public Policy at the Harvard Kennedy School. He is a cryptographer, computer security professional, and privacy specialist. He has been called a "security guru" by The Economist.

Below, Bruce shares 5 key insights from his new book, A Hacker’s Mind: How the Powerful Bend Society’s Rules, and How to Bend them Back.

1. Hacking is ubiquitous.

We normally think about hacking as something done to computers, but any system of rules can be hacked. Take the tax code as an example. It’s not computer code, but its code is a series of rules, of algorithms. It has vulnerabilities—we call them loopholes. It has exploits—we call them tax avoidance strategies. And there is an industry of black hat hackers finding exploitable vulnerabilities, whom we call tax attorneys and tax accountants…

Why the U.S. Should Not Ban TikTok

The ban would hurt Americans—and there are better ways to protect their data.

Congress is currently debating bills that would ban TikTok in the United States. We are here as technologists to tell you that this is a terrible idea and the side effects would be intolerable. Details matter. There are several ways Congress might ban TikTok, each with different efficacies and side effects. In the end, all the effective ones would destroy the free internet as we know it.

There’s no doubt that TikTok and ByteDance, the company that owns it, are shady. They, like most large corporations in China, operate at the pleasure of the Chinese government. They collect extreme levels of information about users. But they’re not alone: Many apps you use do the same, including Facebook and Instagram, along with seemingly innocuous apps that have no need for the data. Your data is bought and sold by data brokers you’ve never heard of who have few scruples about where the data ends up. They have digital dossiers on most people in the United States…

Everything Is Hackable

Every year, an army of hackers takes aim at the tax code.

The tax code is not computer code, but it is a series of rules—supposedly deterministic algorithms—that take data about your income and determine the amount of money you owe. This code has vulnerabilities, more commonly known as loopholes. It has exploits; those are tax avoidance strategies. There is an entire industry of black-hat hackers who exploit vulnerabilities in the tax code: We call them accountants and tax attorneys.

Hacking isn’t limited to computer systems, or even technology. Any system of rules can be hacked. In general terms, a hack is something that a system permits, but that is unanticipated and unwanted by its designers. It’s unplanned: a mistake in the system’s design or coding. It’s clever. It’s a subversion, or an exploitation. It’s a cheat, but only sort of. Just as a computer vulnerability can be exploited over the internet because the code permits it, a tax loophole is "allowed" by the system because it follows the rules, even though it might subvert the intent of those rules…

We Don’t Need to Reinvent Our Democracy to Save It from AI

When is it time to start worrying about artificial intelligence interfering in our democracy? Maybe when an AI writes a letter to The New York Times opposing the regulation of its own technology.

That happened last month. And because the letter was responding to an essay we wrote, we’re starting to get worried. And while the technology can be regulated, the real solution lies in recognizing that the problem is human actors—and those we can do something about.

Our essay argued that the much heralded launch of the AI chatbot ChatGPT, a system that can generate text realistic enough to appear to be written by a human, poses significant threats to democratic processes. The ability to produce high quality political messaging quickly and at scale, if combined with AI-assisted capabilities to strategically target those messages to policymakers and the public, could become a powerful accelerant of an already sprawling and poorly constrained force in modern democratic life: lobbying…

The Big Idea: Bruce Schneier

The world has systems. Systems have rules. Or are they more like guidelines? In today’s Big Idea for A Hacker’s Mind, security expert Bruce Schneier takes a look at systems, how they are vulnerable, and what that fact means for all of us.

BRUCE SCHNEIER:

Hacking isn’t limited to computer systems, or even technology. Any system can be hacked.

What sorts of system? Any system of rules, really.

Think about the tax code. It’s not computer code, but it’s a series of rules—supposedly deterministic algorithms—that take data about your income and determine the amount of money you owe. This code has vulnerabilities, more commonly known as loopholes. It has exploits; those are tax avoidance strategies.

Opinion: What Peter Thiel and the ‘Pudding Guy’ revealed

  • February 7, 2023

The Roth IRA is a retirement account allowed by a 1997 law. It’s intended for middle-class investors and has limits on both the investor’s income level and the amount that can be invested.

But billionaire Peter Thiel and others found a hack. As one of the founders of PayPal, Thiel was able—entirely legally— to use an investment of less than $2,000 to buy 1.7 million shares of the company at $0.001 per share, turning it into $5 billion in 20 years—all forever tax-free, according to ProPublica. (Thiel’s spokesperson didn’t respond to ProPublica’s questions about its 2021 report.)…

How ChatGPT Hijacks Democracy

Launched just weeks ago, ChatGPT is already threatening to upend how we draft everyday communications like emails, college essays and myriad other forms of writing.

Created by the company OpenAI, ChatGPT is a chatbot that can automatically respond to written prompts in a manner that is sometimes eerily close to human.

But for all the consternation over the potential for humans to be replaced by machines in formats like poetry and sitcom scripts, a far greater threat looms: artificial intelligence replacing humans in the democratic processes—not through voting, but through lobbying…
