For over a decade, the expectation that computers would keep becoming faster under Moore’s Law is being questioned as we near the physical limits of shrinking transistors. The consistent miniaturization of transistors has been pivotal in enhancing computer power, but as these transistors approach atomic sizes, their reliability as conductors of electrical current diminishes. However, this doesn’t spell the end of technological advancement. While we continue the process of transistor miniaturization, the future of processor technology lies in innovation beyond transistors, with 3D fabrication presenting as a promising next step.
