Well, the man is revolutionary and looking at the way things are going around, who knows that it comes true as well. Few years ago who thought that we would be able to talk to our GPS systems while driving cars or cars audio systems to make calls or phone banking virtual operators to do phone banking without knowing they are just a virtual voice working on voice generated commands or will be able to talk to Google Home, Alexa, etc.. for home automation or playing music but all this is true now and part of our daily lives...

I know when we talk of Space and sending a car, it is altogether a different game but for me all those things I use today were also unimaginable few years ago :)
