Third, this is a whopping 37MB webpage on initial load. But that’s not the worst part. In the five minutes since I started writing this post the website has downloaded almost half a gigabyte of new ads.

This is so irresponsible and unprofessional it beggars belief. Web browsers ought to defend against this. Why not cap page loads by default at, I don’t know, 5 MB? And require explicit consent to download any additional content?

I hate the term “hallucinations” for when AIs say false things. It’s perfectly calculated to mislead the reader - to make them think AIs are crazy, or maybe just have incomprehensible failure modes.

AIs say false things for the same reason you do.

At least, I did. In school, I would take multiple choice tests. When I didn’t know the answer to a question, I would guess. Schoolchild urban legend said that “C” was the best bet, so I would fill in bubble C. It was fine. Probably got a couple extra points that way, maybe raised my GPA by 0.1 over the counterfactual.

Some kids never guessed. They thought it was dishonest. I had trouble understanding them, but when I think back on it, I had limits too. I would guess on multiple choice questions, but never the short answer section. “Who invented the cotton gin?” For any “who invented” question in US History, there’s a 10% chance it’s Thomas Edison. Still, I never put down his name. “Who negotiated the purchase of southern Arizona from Mexico?” The most common name in the United States has long been “John Smith”, applying to 1/10,000 individuals. An 0.01% chance of getting a question right is better than zero, right? If I’d guessed “John Smith” for every short answer question I didn’t know, I might have gotten ~1 extra point in my school career, with no downside.

You can go further. Consider an essay question: “Describe the invention of the cotton gin and its effect on American history, citing your sources.” Suppose I slept when I should have studied and knew nothing about this. A one-in-a-million chance of getting it correct is better than literally zero, right?

The cotton gin was invented by Thomas Edison in 1910. It was important because gin made with cotton, of which the Southern plantation economy produced a surplus, was cheaper than the usual gin made with juniper berries. This lowered the price of alcoholic spirits considerably. According to historian John Smith in his seminal The Invention Of The Cotton Gin For Dummies, the resulting boom in alcoholism provoked a backlash that ultimately led to Prohibition.

I won’t say no human has ever done this, because I remember one kid doing it during a presentation in twelfth grade. It was so embarrassing (for him) that it remains seared in my memory - which sufficiently explains why most of us don’t try it. A one-in-a-million chance of a better grade isn’t worth the shame of a 999,999-in-a-million chance of sounding like an idiot.

AIs have no shame. Their entire training process is based on guessing (the polite term is “prediction”). It goes like this:

1. AIs start with random weights, ie total chaos.

2. They’re asked to predict the next token in a text.

3. They give a random answer.

4. When they get it wrong, the training process slightly updates their weights towards the pattern that would have gotten it right.

5. After trillions of tokens, their weights are in a good, nonrandom pattern that often predicts the next token successfully.

But even after step 5, they’re still guessing. Consider the following sentence: “I went out with my friend Mr. _______ “. With your human knowledge, you can predict that the token in the blank will be a surname. But you have no way to know which. If your life was on the line, you might guess “Smith”, since it’s the most common surname. Even the smartest AI can do little better.

And over the massive training process, even the craziest guesses sometimes pay off. Imagine you took one hundred trillion history classes. One in every million times you wrote a fake essay like the one above, your teacher said “Great job, that was exactly right, here’s a gold star.”

So the interesting question isn’t why AIs hallucinate: during training, guessing correctly is rewarded, guessing incorrectly isn’t punished, so the rational strategy is to always guess (and increase your chance of being right from 0 to 0.001%). Since AIs in normal consumer use follow the strategies they learned during training, they guess there too. The interesting question is why AIs sometimes don’t hallucinate. Here the answer is that the AI starts out hallucinating 100% of the time, the AI companies do things during post-training to bring that number down, and eventually they reduce it to “acceptable” levels and release it to users.

How do we know this is what’s happening? When researchers observe an AI mid-hallucination, they see the model activates features related to deception - ie fails an AI lie detector test. The original title of this post was “Lies, Not Hallucinations” and I still like this framing - the AI knows what it’s doing, in the same way you’d know you were trying to pull one over on your teacher by writing a fake essay. But friends talked me out of the lie framing. The AI doesn’t have a better answer than “John Smith”. It’s giving its real best guess - while knowing that the chance it’s right is very small.

Why does this matter? I often see people in the stochastic parrot faction say that AIs can’t be doing anything like humans, because they have this bizarre inhuman failure mode, “hallucinations” which is incompatible with being a normal mind that has some idea what’s going on. Therefore, it must be some kind of blind pattern-matching algorithm. Calling them “shameless guesses” hammers in that the AI is doing something so human and natural that you probably did it yourself during your student days.

Understood correctly, this is a story about alignment. AIs are smart enough to understand the game they’re actually playing - the game of determining strategies that get reward during pretraining. We just haven’t figured out how to align their reward function (get a high score on the pretraining algorithm) with our own desires (provide useful advice). People will say with a straight face “I don’t worry about alignment because I’ve never seen any alignment failures . . . and also, all those crazy hallucinations prove AIs are too dumb to be dangerous.”

Energy affordability has become a defining kitchen-table issue across the country and especially in the Mid-Atlantic, where it was top of mind for voters in races for governor in Virginia and New Jersey. In D.C.’s mayoral election this year, it’s likely to be a top issue, given the sharp utility rate hikes approved by regulators.

Energy costs are up across the nation, and the problem is particularly acute in D.C., where electricity rate increases approved by regulators have dwarfed those of Mid-Atlantic states. From 2017 to 2025, D.C.’s average residential electricity rates soared by nearly 70%, more than double the rate increases in Virginia and Pennsylvania and roughly 50% more than increases in Maryland. 

Surging electricity demand from data centers contributes to the problem, but it does not fully explain D.C.’s outsized rate increases. Virginia is considered “the data center capital of the world,” but D.C.’s electricity rates in recent years jumped twice as much as those of Virginia's largest utility despite the District’s lack of major data centers.

Part of the blame lies with the Public Service Commission (PSC), which regulates D.C.’s monopoly gas and electric utilities, and has approved rate increases that fueled the skyrocketing costs. In 2024, the PSC approved a multi-year plan allowing Pepco to collect $123 million in additional revenue, which will raise the average customer’s monthly bills by $11.34 per month — roughly $136 per year — once it’s fully implemented. This is despite the fact that the utility failed to detail exactly how the money would be spent.

One PSC commissioner voted against the electricity price spike, describing it in his dissent as “a regulatory trainwreck that unreasonably promotes Pepco’s interest at the expense of ratepayers.” He said the rationale for the rate hike “could be summarized as ‘because Pepco said so.’” The D.C. Court of Appeals last week tossed out the 2024 multi-year rate hike because the PSC failed to address factual disagreements over calculations Pepco used to calculate its rate increases. 

The Public Service Commission is an independent agency, meaning that while the mayor nominates and the D.C. Council confirms the commissioners, they do not report to the mayor like most agency leaders. But the council passes laws setting the statutory framework that the PSC must follow and holds annual oversight and performance hearings. 

From 2017 to 2025, that duty fell to Kenyan McDuffie, the former councilmember and current candidate for mayor who chaired the committee with oversight of the PSC. I have attended and testified at every PSC oversight hearing since 2019. I watched as McDuffie lobbed softball questions at the commissioners, such as, “Let me know whether you think the commission struck the appropriate balance” on utility regulation. Not surprisingly, the PSC chair thought the commission had indeed “struck the appropriate balance” on questions of rising costs. 

Despite McDuffie's minimal oversight while leading the committee that supervises utility regulators, he nonetheless acted vigorously on utility issues. In 2018, he stripped from a landmark energy law a provision that would require Pepco to lower electric bills with long-term contracts for renewable energy. At the time, Massachusetts projected savings of $682 million from requirements similar to those that McDuffie removed. But Pepco was on the same page as McDuffie, with the utility even running misleading ads about it on Facebook.

With McDuffie’s resignation from the council to run for mayor, PSC oversight has shifted to the committee chaired by Ward 6 Councilmember Charles Allen. He could pass legislation to slow or stop utility rate increases.

Most D.C. residents are not thinking about utility regulation when they look at their monthly bills to try to figure out how to keep up with D.C.’s rising costs. But decisions made by regulators and elected officials directly shape the bills families have to pay. Kenyan McDuffie could have scrutinized utility rate hikes and defended struggling ratepayers. Instead, he sided with utilities. Now D.C. families are paying the price.
