I think improving the efficiency and logistics of delivery services actually qualifies as 'an important thing'. It might not be as sexy as curing cancer or eliminating poverty, but it provides a service that allows individuals the opportunity to maximize their own productivity, which has both economic and quality of life impacts. While this service isn't exactly revolutionary, it could put pressure on competitors to improve their customer experience. I think the end game (as does Amazon apparently) is sub-30 minute deliveries done using energy-efficient and autonomous technology, but that is a ways away, but at the very least, incremental improvements by upstarts will put pressure on the industry as a whole to improve their services (think about it, why doesn't Fedex/UPS already offer evening services to residential areas, they should have been doing this years ago).
