100% not safe ... Even human beings cause occasional mistakes!
But, if robots and drones become so popular, I feel like people's work is gone ...
There is not such a thing. Work of people is also moderately left.
The other thing is cost. The cost of the delivering robot now is at least one car ...(Interview)It is necessary to some extent also the useful life I wish the price will be cheap by mass production and competition due to popularization
By the way, Will it be a solution to the shopping vulnerable problem?
I hope so ... I think it is quite difficult as it is now.
As I mentioned earlier, home delivery robot and home delivery drone have short running times and can not go far away unless they are carried by truck. I think that operating time will increase if it is made bigger, but that will also increase the risk of accidents happening. Especially since the drones are flying over the head, it is not possible to increase the size considerably when considering the risk of the crash, and there is a problem that the place to take off and landing can not be secured if the size is increased.
I think that there is an opinion that it makes automatic trucks, but when doing so, the work will be extremely reduced and the number of unemployed people will increase. It is necessary to make sure that this balance is not mistaken how much leaving person's work and how much it leaves to the machine. Of course, the development of technology is also indispensable.
