Yesterday I participated in my first (possibly last?😅) Hyrox, in the men’s open doubles. Hardest physical activity I’ve ever done. Really thankful for my Dad Bod Squad for motivating me to do hard things.

An AI cautionary tale told through some Claude screen shots and a few Slack messages, with some political editorializing on my part.
Me asking Claude how to spell "seventeen" and Claude getting it wrong.Claude explaining why it couldn't spell "seventeen", with the closing line: "The fix, basically, is forcing myself to do the boring mechanical thing (spell it out, tag each letter) rather than trusting an intuitive-feeling answer."My saying that based on the previous answer, AIs are Republicans.

Eric,

Thank you so much for your monetary gift to support my Imagination Library. This program is so special to me and I am thrilled that it is special to you, too. My Daddy was the inspiration for the Imagination Library and he told me many times that out of all of the dreams I had fulfilled, this program was the one thing that made him the most proud of me!

Yesterday, a group of fellow middle-aged friends (aka The Dad Bod Squad) and I finished a Spartan Super 10K. I ended up running well over 10K due to a few penalty loops for obstacles I couldn't quite finish. This is how my mid-life crisis is manifesting, and I'm okay with that😅

You may have to zoom in a bit to see it, but on my morning walk to work I discovered a scenario that perfectly embodies a pessimist’s view on life.

Read the intro to @chanda.blacksky.app’s new book while waiting for her to speak at Harvard last night, and these two paragraphs alone should convince you that this is a book you need to read.
Cover of Chanda Prescod-Weinstein’s book The Edge of Space-TimeExcerpt from intro:

When it's at its best, physics is a kind of poetry, a story about the cosmos that is made from metaphors-and a producer of metaphors in its own right. I believe that seeing the universe through the perspective offered by physics strengthens our ability to understand what work metaphors are doing on us and how we might wield them. It is in this sense that physics works on us like poetry: a way of understanding the world that provides insights not available to us elsewhere.
This helps us see why we should bother with it. We should bother with physics because it is, in part, how we as a species learn to use our minds. We should learn and teach poetry, physics, algebra, and other abstract ideas because they train us to think in symbolic and figurative terms. The same goes for calculus and quantum mechan-ics. And if we cannot learn to think in and through the abstract and the symbolic, then we are pliable. We are sitting ducks for the fascists and authoritarians who will use us for their ends, and their ends are ultimately catastrophe for the rest of us. That's always been true, and it always will be.

My 13yo is currently at a Model UN summit at the actual UN in NYC with other 6th-8th graders and these are the subtopics for discussion in one session 😲. If she understands what all (or any?) of these things mean, she is way more politically savvy than I am.

This piece by David William Silva sums up a lot of my thoughts about AI much better than I ever could have. substack.com/home/post/p-... This section in particular articulates my biggest fear when people tell me they used AI for "creative thinking". It's not brainstorming. It's pattern recognition.
The Brainstorming Test
I have used AI many times as a brainstorming mechanism, a sounding board for early-stage ideas.

And here is what I’ve found: every time I had an idea that was genuinely outside the box, AI discouraged me from pursuing it. When I persisted, it didn’t just push back, it practically begged me to stop. To not continue. To not insist.

Think about what that means. The tool that everyone tells you is “creative” and “revolutionary” is architecturally incapable of doing anything other than averaging what already exists. It is a statistical summary of the past masquerading as a window into the future.

When it tells you your unconventional idea is bad, it’s not evaluating your idea. It’s telling you that your idea doesn’t resemble the data it was trained on.

That’s not intelligence. That’s pattern-matching with a confidence problem.

I can’t stop thinking about this paragraph from Kaveh Akbar’s “Martyr!”, and saddened by the fact that the government can’t even get the “don’t be shitty” part right.
WHEN ASKED ABOUT THE DIFFICULTIES OF SCULPTURE, MICHELAN-gelo said, "It is easy. You just chip away all the stone that isn't David." It's simple to cut things out of a life. You break up with a shitty partner, quit eating bread, delete the Twitter app. You cut it out, and the shape of what's actually killing you clarifies a little. The whole Abrahamic world invests itself in this promise: Don't lie, don't cheat, don't fuck or steal or kill, and you'll be a good person.
Eight of the ten commandments are about what thou shalt not.
But you can live a whole life not doing any of that stuff and still avoid doing any good. That's the whole crisis. The rot at the root of everything. The belief that goodness is built on a constructed absence, not-doing. That belief corrupts everything, has everyone with any power sitting on their hands. A rich man goes a whole day without killing a single homeless person and so goes to sleep content in his goodness. In another world, he's buying crates of socks and Clif bars and tents, distributing them in city centers. But for him, abstinence reigns.
