Some folks say, “Technology’s great! So many new ways to connect people and businesses!” Others say, “Help! My grandkids are so obsessed with their devices, they rarely talk to me unless I pester them!” Drawing on Tim’s recent Trenton Computer Festival talk on 3D Printing, and new research by Prof. Jean Twenge, this Dialog explores “Puzzles to Ponder” in both new technology and human relations.

Are Adults "Lonely" Too?
- "Still Bowling Alone" (6/15/15)
As social structures (PTA,
Church, Political Parties)
have disintegrated, we are
more disconnected from each
other.
- Do you trust most people?
1970: 50%
2012: 33%
- How often do you spend time
with your neighbors?
1970: "2x/week"
2012: "Never"
"Yes":

Action Anyone?
"Five Science-Backed Ways to Break Our Phone
Addictions" by Eric Barker
1. Use "I Don't..." instead of "I Can't...":
Be the kind of person who says, "I don't check my phone more than
once an hour", instead of, "I can't check..." (Success rate: 80% vs. 10%!)
2. Proximity is destiny:
Put your phone across the room and laziness becomes a superpower!
3. Use a Stopping Rule:
Our phone have a countdown timer - use it to signal it's time to stop
social media!
4. Don't break habits; Replace them:
Keep "good" apps like Kindle or Audible books front & center.
"Time-sink" apps must be downloaded each time you want to use them.
5. Dr. Jekyll, prepare for Mr. Hyde:
At Thanksgiving dinner, exchange phones across the table & make sure
you don't know each other's screen unlock code!
