Are you really arguing that we should have no boundries on progress for fear of a rogue asteroid destroying us all? Shouldn't we consider the risks along the way of what we may accidentally break or purposely misuse along the way? Scientific knowledge comes with risks, both in how the tools can be used as well as errogant or misguided belief that we know enough to understand all meaningful implications of wielding said knowledge.

Even the concept of progress as a goal seems misguided and risky. We shouldn't assume something is better simply because it isn't what we had before. "Not worse than what we had before" is a great goal but one that requires effort and focus, it isn't a given law of the universe that all change is good simply because it's change.
