Cost of Trump's D.C. Occupation: $1.1M per day. Cost to operate public housing for D.C.'s entire homeless population: $169,226 per day. It's not about what this country can or can’t afford. It’s about priorities.

This is illustrative of common AI issues: 1) When you get an instant AI answer, it is from a small model, which are weak models, especially at math. 2) Non-reasoning models, like the one powering AI overview, only “think” as they write, they make mistakes & then back justify them as they write more

They’re not banning books because they’re dangerous—They’re banning them because they expose the truth. 📚 Erased tells the history they tried to bury—& now they’re coming for it. If it’s “too dangerous to teach,” you need to read it. ⚠️Read it before they ban it for good: stan.store/gxldsociety/...

One thing the GPT-4o personality issue demonstrates is that treating AI like every other online product by maximizing for engagement & likeability will have unintended consequences that could cause real problems, both for the usefulness of the models & for the people using them,

Great start to my morning at the AIR Show. Thinking around AI and Media Literacy. Media 1.0 (Human) and 2.0 (human+AI) and Media 3.0 (AI agents) are creating more “media” now than all of history. Kids and adults must learn how to know and be critical consumers. @massp

One of my companies informed me they cancelled a $2m conference in Florida. Why ? They didn’t feel they could pass on the incremental cost of tariffs. So they are cutting expenses. That’s a city that lost a ton of tourism revenue. The cost of tariffs isn’t just the cost of the tariff

The past 18 months have seen the most rapid change in human written communication ever By. September 2024, 18% of financial consumer complaints, 24% of press releases, 15% of job postings & 14% of UN press releases showed signs of LLM writing. And the method undercounts true use.

Science O Saturday at the district tournament. Proud of Will who was the only kid doing 3 events. One even went poorly. It was first but the boys rebounded getting 1st Place in Reflection Relay (well done coach Rob) and 3rd in Weather or Not. Proud of the boy and his team who took 1st place overall!

Donald Trump and Elon Musk’s gutting of U.S.A.I.D. will weaken Washington’s reach, but America was already losing the fight for global influence.

Heartened to be on a webinar with @ACLU of MI to learn their perspective on protections for LGBTQIA+ MI citizens and students in the face of recent EOs. MI Law is very clear about non-discrimination. The ELCRA and other law keeps protections for these students (and adults) in place.
