The Event Horizon Telescope has now completed the first set of observations with an array capable of generating images of known supermassive black hole candidates that resolve their horizon. These provide direct access to both the dramas and the stage of the high-energy astrophysical processes associated with AGN and their consequences for how black holes grow, launch outflows, and even the nature of spacetime. In addition, the primary targets of the EHT are highly variable, known to generate flares and ejections on timescales as short as 30 minutes and extending to weeks. Therefore, we are about to enter an era of dynamical, horizon-scale studies of black hole physics. I will discuss the state of EHT observations, what we hope to learn about black hole physics from the first images, and then how we may combine the next many to obtain unprecedented access to the environments, impacts, and physics of black holes.
