In a world where loss of forward travel means an uncontrolled dive, having energy on tap is life. Unfortunately, scenarios like a slow base to final or a go around in a crosswind don't afford the ability to just trade altitude for airspeed. High density altitude + downdrafts or mountain rotors are another situation where I don't want to be underpowered. The only thing that will be transformative for aviation will be a dramatic improvement in energy density or engine efficiency, be that battery electric or otherwise.
