"Identify which bottleneck is actually physical, not financial When discussing how far AI scaling can go, Zuckerberg distinguished clearly between capital constraints and physical ones: "I actually think before we hit that you're going to run into energy constraints... getting energy permitted is like a very heavily regulated government function... you're talking about many years of lead time." The insight is that capital — even hundreds of billions — cannot compress regulatory and physical timelines. Before assuming money solves a constraint, ask whether the real bottleneck is permitting, physics, or time — because those have no financial shortcut.
