Duncan replies:

I guess I see depreciation as an entirely separate process from production.
In production living labor preserves the _current_ value of the means of
production, and adds new value proportional to the living labor time.
Outside of this process many other factors impinge on the valuation of
stocks of existing assets, which amount to _claims_ to value, among them
ordinary depreciation (wearing out) and moral depreciation (devaluation
because of technical change).

Duncan
