The human brain is an amazing structure. Around 86 billion neurons are organized in dynamic networks that take care of perception, memory, body function, learning ability, language, emotions, rationality and much more. The entire biological miracle needs just twenty watts and thus only a fifth of the energy that the “bioreactor” provides in the abdomen of humans. Man -made technology is very bad in comparison. The data centers, which operate the largest and most powerful neural networks- such as large voice models such as chatt- come with an enormous energy expenditure that is measured in mega or even gigawatts and devours the output of entire power plants.
