a16z发布与前Intel CEO Pat Gelsinger等人的对谈视频，Pat提出能源容量等于经济容量，称美国过去15年因煤电退役与可再生能源新增相抵，全国能源容量基本持平，目前年增速约4%。他认为核电适合作基荷，但可再生能源深度依赖中国，并质疑在无法供电时新建数据中心、购置百万级GPU的意义。对谈还涉及芯片设计、存储带宽、先进封装与铜转光网络等瓶颈。

"Energy Capacity = Economic Capacity"
Former Intel CEO Pat Gelsinger on why America's power grid is the ceiling on growth:
"We went through 10 to 15 years where essentially I was taking coal offline at the rate I was adding renewables, and essentially the nation was flatlined in terms of overall energy capacity."
"So essentially our economic capacity as a nation, flat for fifteen years."
"Even with that, we've gone to maybe increasing our national energy capacity 4% per year. Going from essentially zero to one."
"Nuclear as base load is a fabulous thing that we want to go build more of. Unfortunately all of our renewables have deep dependencies in China."
"Energy capacity somewhat dampens how euphoric we can get on AI. Why build a new data center and buy the million GPUs if I can't power them?"

Former Intel CEO Pat Gelsinger with a16z's Raghu Raghuram and Guido Appenzeller on the next wave of semiconductor innovation and the physical constraints shaping the AI buildout: Drawing on his experience designing Intel's 386 and 486 processors, Pat explains how AI could transform chip design, but also why faster design alone won't solve the industry's biggest problems. They examine the bottlenecks in manufacturing, memory bandwidth, advanced packaging, and power, and why today's explosion of specialized AI chips may eventually consolidate around a smaller number of architectures. They also discuss the potential for new memory technologies, the shift from copper to optical networking, and why energy capacity could become a major constraint on AI growth. Finally, they revisit Pat's VMware years to ask what virtualization might look like when infrastructure is built for agents rather than humans.
