Intended Audience: 
The Solar System exists in a state of marginal stability. Is this an expected outcome? The exoplanet sample is now large enough that we can start to meaningfully address this question. I will present recent work connecting what are possibly the first observations of a planetary system forming within its birth disk to several observed features in the exoplanet sample. I will also discuss a long-standing problem in determining the stability of closely packed planetary systems, and a novel approach using machine learning algorithms that is orders of magnitude faster than direct N-body integration.
