The key is what we are spending our time on, and how we are expending our energy.

We consumed much time and energy in writing this book.

Moreover, each of us needs to consume at least 5 liters of water per day, and everything we eat and drink contains water.

Because you have no idea what these agents can do, how often they intend to run, or how many users run them, there is no way to project which resources they consume.

But both of these concepts are paradoxical in nature. Because, in some scenarios, when we expend energy, we actually gain more of it. And when we spend time, we open more up in our lives.
