Software for general mass-market Consumers [where revenue derives from its use] should primarily include a focus on alleviating highly complex tasks that humans either mentally or physically cannot do themselves. Or at least should no longer have to do themselves as daily cognitive load indulges.
Interfaces (ideally small) should always provide the extremes of executive pathways when presenting these options from the machine to the human. And do so in a way that bridges emotional discomfort between the pilot and the vehicle.
If these crosshairs are tested against market timing, I believe they should provide the utmost of value opportunity.
