The potential cost savings, convenience, and efficiency gains make a strong argument in favor of personalized drone delivery. Immediately many human-based delivery and courier services could be put out of business. Supply chains could be reinvented to support services that still need both a human and drone aspect (such as court filings and within office building deliveries), although amphibious drones could be just around the corner: robotic-on-land and flying-in-air for urban office and apartment building deliveries. Hiro Protagonist is out of a job not due to landing in a swimming pool but due to personalized drone pizza delivery services!
Longer-term implications could include a redesign of how space is used. Personal drone delivery services could become like the pneumatic tubes or dumbwaiters of the past, including the secure vestibule area already envisioned for delivery at home and office entry areas. Downtown traffic and congestion could be significantly reduced. An obvious challenge is quality of life degradation due to noise and the visual detritus of drones. Are human civilizations relegated to becoming the hive substrate for the incessant and pervasive buzzing of personal drones circling as they conduct their business? Hopefully the 'Prius drone' (e.g.; quiet) and pleasing visual design will be part of the modernization. Personal drone delivery could be an important intermediary step on the way to the 3D home printing of all desired objects.
