Right, this doesn't make much sense. You can add fly-by-wire and autonomy to a helicopter as well (it's been done). The two come from different backgrounds, though: people are familiar with "drones" being relatively cheap and easy to fly. So scale it up and add a person, and now it's both easy-to-fly and accessible to your average commuter.

Of course, this reasoning doesn't usually account for the cost of implementing all that safety and redundancy stuff that was previously just understood to be possible. Not to mention the cost of getting it FAA-certified when you're done.
