Hi Yasir, 

If you take the iPhone for example. It is ten years and we have moved from the 1st generation to the iPhone 7. However, the way we interact with the isn't massively different. It's still touchscreen, we need to look down at it, we make calls, browse the web and apps etc. But if we are to believe the emerging trends, we will have massive IoT, AR/VR, more AI etc. How will this change the way we interact with the phone. Or in 10 years time will the iphone still be a smartphone, just more powerful with additional functionality? I hope this somewhat clarifies the questions.

@Venkatesh thanks

Thanks very much Yasir
