In this special edition of Shared Everything, we've assembled some of our favorite conversations on the engineering challenges reshaping AI infrastructure. From power generation and rack density to cooling, networking, efficiency, and even the possibility of datacenters in space, these discussions explore how every layer of the modern AI stack is evolving. Featuring Renen Hallak, CEO and Cofounder of VAST Data, on why next-generation AI datacenters will be designed around power, including dedicated generation and nuclear energy; Jonathan Koomey, internationally recognized researcher on computing and energy, on the history of datacenter power consumption and why AI could ultimately drive greater efficiency; Ken Patchett, VP of Datacenter Infrastructure at Lambda, on building facilities that can keep pace with rapidly evolving AI hardware; Rich Miller, Founder and Editor of Data Center Frontier, on the architectural changes spanning power delivery, cooling, networking, and high-density AI deployments; and Dan Nishball, Research Analyst at SemiAnalysis, on the economics and total cost of ownership behind the emerging concept of space-based datacenters.
