The Next Generation

摘要

Most who read about the old copper and insulator PCBs are amazed at how far we have come. In fact, some are surprised that useful products were even possible with such simple printed wiring technology. Today, nearly all conductors are made with organic materials, as are many of the devices, especially the nanodeposited structures. While electrons are still used, photons are more dominant, although the full-photonic computer is still years away. Many predicted that the light-powered computer would replace the old electronic version by 2050, but this won't happen simply because electrons are very good at so many functions, especially storage.
