What navigation technology is still needed?

I remember just a few years ago we used relatively simple chartplotter units. If we wanted chart updates we had to buy a new chip. Ten years ago there was no such thing as an app that you could use for navigation muchless one that would seamlessly communicate with your chartplotter. Now you can create your own charts with technologies such as SonarChart Live and sync your app (on phone or tablet) seamlessly with your chartplotter (like the seamless integration of the Navionics app with the Raymarine wifi enabled chartplotter).
It really baffles me how far navigation technology has come in the last decade.

What technologies do you think they'll come out with next? What features and capabilities do you think are still needed?
