It's (1) a loss of expected value (2) misspent resources.
You spent $X to buy RAM chips, expecting that you could produce $Y with it. But you didn't. So you (1) failed to realize the expected value $Y, and (2) misallocated $X, which in hindsight you would have used differently.
Again, that's all learning that future expectations do not match reality.
The decision/action happened earlier, and is separate from the realization. Attributing the material loss to the realization is misplaced.
