Immer noch unterliegen wir im 21. Jhd. den systemischen, soziopolitischen Turbulenzeffekten des Kapitalismus.

Immer noch sehen wir alle 50-80 Jahre Kriege, um die Wirtschaftssysteme zu befeuern.

Immer noch fΓΌhrt die exponentielle Arm-Reich-Schere zur gesellschaftlichen Spaltung.

Es wird Zeit‼️

Damit begrΓ€bt sich auch immer mehr die Hoffnung eine tolle proaktive CDU/SPD Politik wΓΌrde uns vor einer rechtsextremen Regierungspartei schΓΌtzen.

The sad news for πŸ‡©πŸ‡ͺ is: After 80 years of the 2nd world war: we will see an right-wing extremist Party in the parliament again.

Ein Friedrich Merz ist kein Krisenkanzler. Wer mit Themen wie BΓΌrgergeld (CDU Idee) abschaffen und Krankheitstage bestrafen, Symbol- und Marginalthemen angeht, statt Milliardenverluste durch Steuerflucht und fehlende Wirtschaftsimpulse zu beackern, wird πŸ‡©πŸ‡ͺ nicht gestalten.

Es wird immer klarer: Eine CDU ist keine Reformationspartei, sie ist Verwalter von schΓΆnen Zeiten in denen Deutschland ein SelbstlΓ€ufer ist.

Hinzu kommt eine visionslose SPD, die keine Perspektive fΓΌr eine zunehmend automatisierte Wirtschaftswelt anbieten kann und personell eine Katastrophe ist.

Ad-driven filters are like robots on a market place that group people in zones and surrounds them by posters.

Nobody looks at the posters but becomes more extreme in their opinion within their bubbles.

Visitors to the bubble are talked down to silence.

This is not a normal social habitat.

At the European Parliament:

‼️Forbid ad-driven content-filter on social media‼️

Why?! Because it destroys our democracy and destabilizes our society.

Strong and healthy democracies needs space for social- and self-correction. It needs a market place where everybody can talk to everybody.

Universal dimensions of visual representation Probing neural representations reveals universal aspects of vision in artificial and biological networks.

The most brain-like representations of visual neural networks are also the most universal ones, i.e., they are largely independent of a network’s architecture or training. Cool new work by Chen & Bonner in #ScienceAdvances! #neuroAI

Merry Christmas Season from the Smart Photonics Research Group in Jena @leibnizipht.bsky.social

This beautiful speckle Christmas sphere was measured by our Master student Yuze Wu. Would love to have one of those on my tree in real. πŸŽ„

Me every time I hear one of the large laundry machine business guys talking about being close to artificial general intelligence.

Let’s face it: LLM scaling is over. Research is needed. Into new models and fundamentally new hardware approaches.

The future is light. πŸ’‘
