You won't believe how far technology has come if I;m to start pointing out. We were once in the days of camera phones without camera and had poles, to the days of low resolution camera phone. Down to bigger screens, now front selfie-based camera. We're now in the times of Dual-camera meanwhile Tri-camera is on the way.
Who knows what the future holds, flying cars are even now available for commercial use.
You don't do the same old thing and expect a progressive change. In life you just have to do something new because new is always better.
