Nature still outperforms the most powerful computers in routine functions involving perception, sensing and actuation like vision, audition, and motion control, and is, most strikingly, orders of magnitude more energy-efficient than its artificial competitors. In this paper, some basics of neuromorphic electronic engineering and its impact on recent developments in
