It's 2018; generally speaking, which types of life's problems are solved by having a cell phone/smart phone/mobile phone? ~

Having a land line was not and is not a problem.  That is the safest and most secure way to communicate outside of one to one physical communication.

No longer have to drive around lost trying to read a map not knowing where you are :(

This just seems like laziness to me.  

No longer need to describe just send pic.

I was only guessing.  I don't own a mobile phone.

Those lists are so heavy.  Sorry, that is not a problem.  ;)

That wasn't a problem before mobile phones.  People communicated just fine.

Agreed. But that was before the instantaneous, real-time worldwide contact we now have in our hot little hands. People communicate incessantly now. 

The word 'incessantly' connotes negativity. Therefore, this could be an answer to Randys other question.

I wouldn’t say it’s necessarily a bad thing, but can easily become so. I think of the fools who post every waking moment of their lives on-line.

  Wait, you mean you don't want to see the new hair color Mom has chosen this week or peanut butter and jelly sandwich some kid is about to eat or vacation photos at the resort hotel or a complete stranger's newborn child or a speeding driver rant at the police officer who's issuing the citation or a swimming competition in Beijing or Little Biff getting a haircut or how Paw mowed the lawn in perfect symmetry or granddad drifting off to sleep in the rest home or a mom crying as her child starts kindergarten or the skateboard pratfalls of misguided youth or every bowel movement a college freshman makes or the latest tattoo that's been plastered in someone or the clothes a teen bought at the mall or . . . 

Yep, that’s one way of saying it. 

No they don't.  The art of communication is suffering.  Just because people are playing with their little dufus gadget, communication is not assumed.  

Aye, indeed. We're back in the first grade, lol.
