For the most part, I'm bullish on life. The issue is we couldn't anticipate the consequences that will come about as a byproduct of our advancement as a civilization. Maybe a few do and decided to do nothing about it. But I think the future looks bright considering how far we've come in bettering our way of living and the tools we have at our disposal.
The future seems and looks bright, but the advancement of evil in people will continue and this itself is scary. It feels like evil grows with how enlightened the world becomes.
