According to Jeff Dean, David Patterson highlights in his Communications of the ACM article that approximately $100 million in federal funding over 40 years enabled the creation of foundational technologies like RISC, RAID, and cluster computing software. These technologies have been pivotal to the rapid advancement of artificial intelligence and large-scale data infrastructure. The article estimates a 1000X return on investment to taxpayers, underlining the critical role of government-funded academic research in powering high-impact AI systems and business applications. This demonstrates the immense business and societal value generated by strategic public investment in computing research (source: Communications of the ACM, Jeff Dean on Twitter).
