We still have Gallium Arsenide (0.3V PN junction barrier), electron beam lithurgy, stacking up, and finally going back to efficient bare-metal coding. Still a magnitude level performance increase to go, but at a magnitude increase in cost. We might be at the economic sweet spot right now, it only gets more expensive from here …
