Ask HN: Whatever happened to the “coming wave” of delivery drones?

I feel like a few years ago all the rage was that Amazon and other retailers were going to deliver things via drones, straight to your doorstep

Food delivery companies as well seemed to be testing out robots that would bring your food to you albeit in a more sidewalk bound way

Its been a few years and I have yet to have a single thing drone delivered to my house

What happened to that alternate future? Are companies still working on it? Or did we move on from that idea for some reasons we discovered?
