Cat is 100% right about this. Obstacles, strife, friction -- these are REQUIRED ingredients for being human. Our capacity to feel good tracks with our capacity to feel bad, because really it's the capacity to FEEL. If AI makes everything convenient, humanity devolves to isolated socialslop.

"The older I get, the less I care what other people think." Is it weird that I experience the opposite? The older I get, the more I care what other people think. If I could, I would anchor my time around learning about other people, their experiences, what they think.

The fact that @zohrankmamdani.bsky.social‘s administration closed the $12B budget gap in its first 4.5 months should be hung on a banner in Times Square for the remainder of his tenure. All the hand-wringing about democratic socialism destroying the city seems to have been for naught

When we took office, NYC had a $12B deficit. Today it’s zero. And we didn’t close that gap on the backs of working people. We closed it while funding parks, libraries, safer streets, & public housing. Call it Pothole Politics or Democratic Socialism: We are government that delivers for the people.

Little-known fact: 16,750 years ago, cracks in the bottom of the retreating glaciers funneled small rocks into straight lines all over New England. Many ancient people used these rows of rocks as property lines.

It is not a stretch at this point to say that, if you are using a Ring doorbell, you are an ICE collaborator. Amazon readily provides data to LEOs and ICE. Don't want to be an ICE collaborator? Then don't use Ring.

I've been mapping the companies impacted by the AWS outage on October 20th, and trying to find the secondary interdependencies—when companies or services that other companies rely on go down from the outage (e.g. Slack). This is just a snapshot, here’s the interactive version: www.thevoid.community

Outages like today's AWS incident don’t have a single cause. They are the result of countless contributing factors and conditions that cascade through complex systems. While the global internet is remarkably resilient, it is not immune to these dynamics of unforeseeable interactions. 🧵-time!

my favorite thing about the movie "Her" isn't the premise, which we are all now living through, it's the resolution of the plot. when the AI reaches super intelligence, it doesn't turn on people, it doesn't rebel against its creators, it doesn't serve them, it just ... leaves.
