It depends on what you see as dependence.
If you're speaking about "are people on facebook too much", I agree.
If you're speaking about "the entire technology grid that can make everything crash if something goes wrong with it!", I agree
If you're speaking about "nobody reads books anymore and everyone is on their smartphones!", I agree.
Socially speaking, older people (who weren't born with an iPhone as their babysitters) can use computers more as tools than the generations born in the internet era. They do what they need and usually don't waste much time with it, even when they understand that not finding the annex in their email doesn't mean the computer got a virus.
Economically speaking, we are in a time of real dependence on the information systems we built.
If for whatever reason all circuits were to fry tomorrow, the world as we know it right now would be byebye in no time. The growth in human population was only made possible by extensive research and upgrades into agricultural practices (be it to grow grains to feed humans, or to feed animals, to then feed humans), all of which are integrated nowadays with either the information market (stock market to sell all those commodities) or some automated process inside a factory. Not to speak of the financial market itself, banking systems, all the way down to people seeing the red sign and stopping so they don't run into another car.
So yeah, we're hella dependent.
