Because of the physical limitations of silicon-based circuitry, there is an upper limit to how powerful a modern computer can be made. In response to this, researchers have been looking into other mediums to build faster and more powerful computers from, including using quantum-based processors, and neurological chips based on human brain cells. Another promising idea, based on DNA, plans to utilize the otherwise naturally-occurring computer of genetics.
