Energy, Time and Information
To accomplish any given task, you can use a mix of three “pure” capabilities:
– unlimited knowledge and no time or energy
– unlimited time, but zero knowledge or energy
– unlimited energy and zero time and knowledge
e.g. you know something and you try to use it in the real world. It doesn’t work, so you add some combination of more knowledge, brute force, or just time (trial and error) to make it work
