I suppose I could say that Tesla is a "hero" to me. I want to invent things that will significantly improve the world. The only problem is that these kinds of devices would be very hard to market effectively, as the "free energy through the sky" thing that Tesla made.
This is also the problem I have with everything. We can see that Tesla really had a love and passion for what he did. He was so passionate to invent things that he neglected his own sanity for the purpose of helping people. Honestly, he is more impressive than the "great heroes" of the past, like Edison, Washington, Lincoln, etc.
I wish that I could have that same passion for something, anything really. Instead, I think about the possible outcomes and find that most anything will end up taken by money-hungry businessmen and distributed only to the wealthy when so many people could be helped. Then there's the point that these people will take it for granted and dismiss the real value of what has been done.
It's sad. I hate humanity. Yet I still love people. It conflicts.
