4 years ago, when I was on the Mississippi, I flew a drone each day to get shots for our short film. When I bought the drone, it came in a carry-on sized box, and cost about $1,500.
Today, I received a recommendation from Amazon for a foldable drone that films in 1080p HD for $50.
Sure, there are non-trivial differences between the two, but the 97% reduction in price blew my mind; especially considering the basic functionality—flying a drone and filming video—is the same.
It reminded me of the concept of the experience curve: with every doubling of cumulative production, the cost of production lowers by a predictable percentage.
If such massive change can occur in the cost of drone technology in 5 years, it gets me thinking about what we can expect to see over the next 5-10 years across other hardware devices.
