There could be limitations on scaling the transistors as we approach nono-meter sizes, but there are other ways to sustain the Moore's Law and economies of scale; like 3D stacking, focus on specialized architectures like GPUs, TPUs, etc. and of course, the ongoing research on quantum computing which will also pay off some day.
