In 2018, more than 1.5 billion US dollars have been invested in AI Circuits from silicon valley. Big companies (Apple, Google, Samsung, Amazon, etc) are pouring even more money to develop Circuits for AI. Why? Because circuit is the biggest bottleneck in AI. The progress in AI cannot continue without the advancement of circuits that form the core foundation of neural networks and machine learning. Circuit is and will continue to be the hottest area in AI for the upcoming future.
