There’s no need to drill down ultra deep if you leverage recent advances in horizontal drilling to creat a series of looping branches off of a central trunk, as it were. Can run a closed loop of circulating fluid too, which offers numerous advantages and obviates risk of fracking related earthquakes, as well as avoiding the corrosion challenges problematic with legacy approaches.
