I am not so sure about that, before the whole weaponization of these drones, drone delivery was the hot topic, then changed to “last mile” delivery when dreams hit reality checks, then the whole “urban mobility” with all the connectivity and drones infra to land and take off, rally points, etc etc, and nothing really changed, connectivity is still a challenge, although there are plenty of work arounds (I am even building a platform that will solve a lot of nowadays drones flight issues), but the endurance? Nope, I remember we always hit this as the biggest showstopper in any mission, especially when these missions usually fly with no infra be it cellular or anything that could charge it. The only solution is scientists find a way to make lightweight high endurance batteries.
