What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
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.
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
