Pleasantly walking along the seine, a beautiful sunny day, suddenly an enticing perfume attracts my attention, my sensors immediately recognise the perfume, I receive instantly an offer from the closest shop selling the same perfume with on the spot delivery via drone and a discount if I buy it right away sgrunt!, while my photosensors take a picture of the lady wearing it and bring up all information about her, from health to interests and financial, the wearables give me advice telling me if I should engage or not in a conversation. Of course her system is doing the same about me and we will have a match or not even before being able to say gulp!
