If I only could accept change rather than be a Luddite, I would be excited for this. But with each new technology, I always ask "Does this make life better and make us happier?"
But the implications of all many companies using drones for delivery would be interesting. Another class of jobs would be eliminated. Google automated cars will drive the trucks, drones will make the final leg. At some point, I could see the only human jobs left are the programmers, designers, and engineers that make all these robots. Next comes the singularity, and humans will no longer be necessary. Hopefully, the robots will not mind me lnving a quiet life in my off grid tiny home.
