Discovery came a lot earlier than people originally thought because of advances in techniques for analysis anything, using things like machine learning. It just made me think how little we can predict the future, which i know you'll agree on. So this idea of what we might be looking back on in another or 20 years from now, it's just so hard to tell, isn't it? Hopefully they will reveal something indeed that is going to allow us to look back and really feel like we've made steps forward.
