Our biggest challenge, as you are aware, in flying fourth-generation and earlier aircraft was understanding what was going on around us, having situational awareness, and then determining, using the small amount of time that was left, how we would react to the tactical situation. With fifth-generation, that situational awareness is presented to the pilot, far decreasing the amount of time and effort it takes to understand what's going on, and giving far more time to make a much better decision and react far better to the tactical situation.
