Depending on how jaded/ cynical/ sci-fi-orientated/ hopeful you are, you might answer:
– No. Complete fantasy.
– I wish. Complete fantasy!!
– Yes. But they will be completely messed up (ie. Watchmen, Heroes).
– Sure. Billionaire anonymous philanthropy is so in.
Of course you could have an answer that says we can all be heroes, if only we can be that person with the courage to do the right thing when the time comes – an idea that Philip Zimbardo explores in one of my favourite TED talks (Youtube link here).
Or you could become one of these guys.
At first you might laugh. Then you might think fake/ setup. Then you might even take a look at their Youtube channel and the related news articles that appear on them. Then you might scoff at the idea of someone anonymously doing good as a con.
And then you might think…does it really matter if it means one person takes a look at themselves and tries to make the world a better place for those around them.
