Interesting work on state-of-art neuromorphic architectures. Clearly, we are still in a brainstorming phase with experimental trials. Obviously, many of these architectures could have been simulated on CPU / GPUs. But practical implementation is a great source of inspiration and professional achievement. Additionally, investors' money wants to see the real thing to close the gap to the market. Fast time to market can indicate whether a promising technology will overcome the natural barriers of entry into application niches. But simulation of architectures can speed up the process and reduce implementation costs of dedicated integrated circuits.
