I’m not even 40 and I remember growing up without internet access, much less a cell phone. I had to walk to a library to use their computers.
I had computers from an early age, but being connected all the time has had a negative impact on me personally. I've started really paying attention and doing the "Digital Declutter" that Cal Newport talks about in his book Digital Minimalism.
I have very very few notifications pop up on my phone now and I'm experimenting more with leaving it at home when I go somewhere. Trying to add a bigger disconnection between me and my phone.
