All that, naturally, is a ways off. As with all big nano breakthroughs (can a nano breakthrough be big?), this tech will take time to smooth out and refine. But the idea of electronically programmable nanocircuitry is tantalizing. Once harnessed, such nanotech building blocks have the ability to create complex circuits at scales and with materials that current manufacturing approaches simply can't achieve. That, in turn, could breed a whole new kind of electronics.
