Excellent portrait of the nostalgia for the days of rule by Moscow in the old GDR that is prevalent in Saxony-Anhalt today and is being manipulated very effectively by the Neo Nazi AfD. Note that most of their voters are young and have no actual recollection of life in the GDR. It's an imagined past

Es wird immer klarer: Eine CDU ist keine Reformationspartei, sie ist Verwalter von schönen Zeiten in denen Deutschland ein Selbstläufer ist. Hinzu kommt eine visionslose SPD, die keine Perspektive für eine zunehmend automatisierte Wirtschaftswelt anbieten kann und personell eine Katastrophe ist.

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.

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 www.science.org/doi/10.1126/...
