2D semiconductor supply chain: From lab to mass production still needs a 'clinical validation' winter

Last week I chatted with an old colleague from United Imaging about AI acceleration chips for next-gen CT scanners. He complained that as silicon processes drop below 5nm, the power wall has pushed cooling solutions to the brink of madness. Yet for us in medical imaging, computing power demands keep rising—a single 3D CT reconstruction model's parameter scale tripled in two years. He dug up a paper for me, saying molybdenum disulfide transistors have energy efficiency an order of magnitude higher than silicon. I asked him: "When can we install this stuff in our machines?" He went silent for three seconds, then said: "Let's wait for the supply chain to finish 'clinical validation' first."
