We start with one basic question, what will you do if you have unlimited wealth? I think that is quite easy to answer. But unlimited wealth is not that 'unlimited', you are still limited by life. So let's move on to the more 'unlimited' (worldly) source which is time. What will you do if you are immortal (assume you are so strong enough that volcano eruption, starvation, and ebola virus won't kill you (or any other cause of death))? I will make the question more specific. Let say that you are immortal, have unlimited time but there are no people in the world but yourself. Adding one more limitation, your start without no man made civilization. No, there is no computer that you are looking at nor even the chair that you are sitting. Can you imagine now? Great, so start thinking read the next paragraph then.
Even though there are some limitations, virtually your source is unlimited. If you persevere enough, you can make a power plant and then computer. But it might take mighty much time, knowing that the whole civilization is represented by just one person. I personally believe that I am not that great to make current civilization, even though I have 100 million years to make all this stuff. What about you?
