I read a trilogy of science fiction novels where an alien attack is imminent on earth after 200 years.  To face them humanities make major scientific advances. They build nuclear fusion and propulsion. But they fail to build Artificial General Intelligence (AGI).  Many scientists consider general intelligence as an outcome of quantum phenomena  https://bigthink.com/hard-science/brain-consciousness-quantum-entanglement/ It is not clear how our ability to reason emerges from our brains. Scientists know how our neurons are connected in our brains.  They know the structure of neurons. But it is not known how the connection between 100 billion neurons in our brain allows us to appreciate art, go to the moon, display emotions, and do so many other things.  Scientists don't know the recipe for intelligence. So they did the next best thing i.e copying our brain architecture. Neural Networks were proposed way back in 1958 by Rosenblatt. But scientists quickly realized th...

Social media is filled with videos of people dropping dead.  Some of it is due to ubiquitous nature of smartphone cameras. We are recording more moments of our time. People had always been dying at an untimely age. Due to smartphone cameras, more such incidents are being recorded.  But it is possible that some of such incidents are side effects of covid.

Covid has become a mild disease due to Vaccine and natural immunity. So we can hope that imp...
