The human mind is the synthesis of many processes operating concurrently. Although a single powerful computer can run concurrent processes, a cluster of independent machines will offer better resilience and scalability

The use of PC technology leverages the massive worldwide hardware and software efforts centered around that platform. Graphics processor units (GPU's) are currently advancing at twice the rate of CPU's. Can this hardware technology in any way help advance AI?

Analyze technology roadmap's of Nvidia, Intel and AMD etc. to estimate the characteristics and performance of future hardware architectures. But the main challenge for AI is software. By current trends, the hardware will be ready well enough in time. It is the software breakthroughs we need right now.
