Totally agree! I’ve learned so much from this talk. He actually referred to it in the SnapCon 2025 keynote youtu.be/U9W04TEMBUk?... when he pointed to the perceptron sprite code and said something like “that’s for another talk”. And a month later that talk showed up.

Astonishing talk by @jmoenig.bsky.social. From teaching linear algebra using powerful examples in Snap!, then replicates (working code!) the history of perceptrons (from Rosenblatt to Rummerlhart), then creates a NN to recognize musical instruments. SO recommended! www.youtube.com/live/_JSnHmG...

So the ceasefire in Gaza isn't real, people are being kidnapped by ICE all over this country, the government is shut down, and millions of people are about to lose SNAP and healthcare and all of these EXACT SAME THINGS would be happening if the Black lady won in November???

Computing has always been a seesawing discipline. We had the AI winters of the 1970s and the 1990s, and we had the dotcom crash and the ensuing “Image Crisis.” It seems another crisis is upon us. Will we ever learn? It is time for some serious thinking! cacm.acm.org/opinion/comp...

I’m reading about Joel Mokyr who just won a share in the Nobel Prize in economics.
(news.northwestern.edu/stories/2025...). He’s an economic historian (!) who explains why Europe got the Industrial Revolution and China didn’t, when China had all the elements (e.g., movable type) before Europe.
