What the article says around this equation
This distinction is especially relevant to claims about artificial intelligence and computing energy. Landauer’s limit is many orders of magnitude below the energy of contemporary digital operations. Datacenter consumption is governed by device capacitance, leakage, memory movement, networking, cooling, utilization, and software workload. Invoking T2 does not by itself predict an accelerator’s efficiency. It identifies a physical floor for a particular logical operation and clarifies why reversible computing is conceptually interesting.
