I don't know why I do this to myself, but somehow resurfacing these cursed images was research for a new piece so now you have to look at them too.

Don't ask me what I'm working on that demanded this, but I've watched the AI-generated video from the Donald Trump Presidential Library and Museum about 20 times today and I'm losing my grip on reality. www.trumplibrary.org

For example, the "critical thinking" frame did more to get people to see not only why history is valuable, but to support greater public funding for museums and historic sites far better than "history reduces prejudice in society" and "history is essential for participating in democracy."

Had an energizing and enlightening few days in Providence, RI for the @aaslh.org / @ncph.bsky.social conference. It was great to connect with so many old and new colleagues from all across the public history ecosystem. History museum people are out here working hard, go visit them.

The Juneau-Douglas City Museum in Alaska is an interesting case. It was a small museum (4 FTE) supported by the city, very typical for history museums. Then the Juneau Assembly cut $260,000 from its budget. Director and curator laid off, one other employee left. Statements from former director:
“That’s what we do. We take care of objects and we take care of our history and the past, and make sure that that’s known, so as we go forward, we have a place that’s rooted – that we know where we’ve come from and where we can go,” Weigel said. And she thinks of the city museum as the community’s museum: “It’s the people’s history; it’s not the City and Borough of Juneau’s history. That’s in there, obviously, but it’s all of our community, and everybody’s stories can be shared there.”

George Washington has more monuments to him than any American but Abraham Lincoln. He doesn't need another now. Nevertheless, here are some photos of George Washington statues from 2020.

To unironically say that we need a Washington statue to show someone who triumphed over oppression is just unbelievable.
Trump said the museum is too focused “on those who have been oppressed” and that there is “no attention paid to those who triumphed over great oppression.” He said Washington would be a good start.

My dog is 14 and for several years has refused to engage with any toy but this one. Every other stuffed toy he’s ever had he has chewed holes in and so he could tear its guts out. This one he only licks. I’m pretty sure he thinks of it as his son.

Cal Newport is not an AI alarmist. But he is a computer scientist, and the tone of his most recent email is incredibly alarming. "As these companies increase their agents’ power, it’s becoming more like mounting Gatling guns on a pack of horses and then letting them loose in Times Square."
All of this should make you angry.

Like many computer scientists without formal connections to Silicon Valley, I don’t believe that LLM-powered agents, on their own, can become superintelligent and create existential risk, as LLM capabilities are more jagged and limited than the average person reading triumphant OpenAI press releases might realize. But you don’t need superintelligence to create a super amount of harm. The combination of unpredictable, non-normative output from unrestricted LLMs and powerful digital tools will inevitably create issues.

(I previously compared equipping long-horizon agents with hacking tools to strapping a weedwhacker to a dog. As these companies increase their agents’ power, it’s becoming more like mounting Gatling guns on a pack of horses and then letting them loose in Times Square.)

Clearly, action is needed. These companies are acting outside market interest with disregard for the safety of the general public, developing tools they explicitly describe as weapons, likely motivated by the anti-humanistic visions of an unsettling ideology. And now they’re bragging about it.

This is not a state of affairs that can long stand.

I wrote about how the Trump administration's new exhibit in Philadelphia recasts Washington as an antislavery luminary rather than an enslaver.
The new exhibit at the President’s House Site offers a profoundly misleading interpretation of Washington’s history with slavery, denying visitors an opportunity to contemplate the irreconcilable tensions between American slavery and American freedom. Rather than focus on the decades he spent actively enslaving other human beings—including while president in Philadelphia—the exhibit now uses Washington’s private statements questioning slavery and his posthumous emancipation of the people he enslaved to diminish the importance of the institution to his life. These revisions distort our history and deprive Americans from encountering history’s full complexity at the site where it happened.Whereas once Washington’s antislavery credentials were wielded to bring slavery to an end, today some conservatives highlight Washington’s ostensible opposition to slavery to deemphasize slavery’s foundational importance in American history. Against a growing insistence that slavery has profoundly shaped American society in ways the country has yet to fully reckon with, they now selectively highlight Washington’s purportedly antislavery views to wave slavery away as a momentary aberration in America’s glorious history of freedom.

I wrote for @theatlantic.com yesterday about how the new narrow, whitewashed interpretation at the President’s House Site distorts a tactic once used by abolitionists and rejects what most people say they want out of history.
These losses are especially acute in Philadelphia. Nearly 175 years ago, Pillsbury, the abolitionist, lamented that Americans heaped praise on Washington while ignoring the enslaved people who made his life and achievements possible. “No glory has ever covered their names; no honor has ever been paid to their memory,” he said. “No monument commemorates their dismal toil.” The President’s House Site exhibit once corrected that imbalance. Not anymore.Many Americans see this whitewashed, censored version of the nation’s past for what it is. Time and again, a majority of Americans express their desire to engage with a full and accurate American history. In Philadelphia, the Trump administration has had to use the power of the federal government to ensure they won’t get it.

Replacing an exhibit about enslaved people at the site of their enslavement with one focused so much on Washington’s antislavery credentials is fundamentally misleading, and it deprives us of a chance to learn about history’s full depth and complexity.

In 1853, abolitionist Parker Pillsbury complained that Americans heaped praise on Washington while ignoring the enslaved people who made his life possible. It took until 2010 to get an exhibit like he described, but now it’s gone, replaced with one that positions Washington as an abolitionist.
“No glory has ever covered their names; no honor has ever been paid to their memory,” he said. “No monument commemorates their dismal toil.” The President’s House Site exhibit once corrected that imbalance. Not anymore.

That number does represent an increase from 10 years ago though. And it held steady from 2017 to 2022 despite a decline in the number of Americans (to fewer than half!) who read at least 1 book. This one via @rbtownsend.bsky.social / Humanities Indicators. www.amacad.org/humanities-i...
In spite of the overall decline in the percentage of American adults reading at least one book each year, their participation in book clubs and reading groups increased (Indicator V-04c). In 2022, approximately 6% of Americans engaged with books in this way, up from 3.5% in 2012. Women were more likely to participate than were men, and the higher a person’s education level the more likely they were to have been part of such a group. Less than 2% of adults with only a high school education participated in a book group, compared to approximately 14% of those with graduate or professional degrees (Indicator V-04d).

In 2022 (the most recent year for which there is data), NEA's Survey of Public Participation in the Arts found 5 percent of Americans participated in book clubs, about the same as 5 years earlier. Obviously doesn't speak to right now though. I guess we'll see if there's a 2027 SPPA...
At roughly 5 percent, meanwhile, the share of adults who participated in book clubs or reading groups in 2022 did not change significantly from five years earlier. In 2022, for the first time, the SPPA asked the nation’s adults whether they had visited a public library: 23 percent reported having done so. Also new to 2022 SPPA were questions about volunteering in general—20 percent of adults did this activity—and participating in community activities, meetings, or events, which also involved 20 percent of adults. Future NEA research will examine the relationship between participating in the arts and some of these other types of cultural and civic activities.
