Hey, do you think what is the next technology trend ? Current trend is crytocurrency, VR, AR , Machine learning and image recogniztion ( tensorflow ) and so on ... For me , i think the next trend will be Drone, E-commerce might use drone for delivery and school might replace by drone, then whole sky will become drone traffic jam ...
It's quite hard to invent smth absolutely new while we have old energy resources
So I'b say really new trend will appear once we have new more powerful batteries
