We shot thousands of tiny cubes into a heights people thought heaven would reside. Then we communicate with them at the speeds of "The whole data storage of 2000's computer" per second. They survive radiation, accelerations and flying through electromagnetic field at thousands of km/h. We can predict their movement, steer them and provide consumer priced service for tens of thousands of people. It's astronomy, mechanical, material, electrical and computer engineering at it's peak.

This is a civilization level defining achievement.
