Modern technology is making us anti-social!
It’s almost like people would rather not talk to every random stranger they see in public.
Phones have much more utility. While in the lower images, they are all reading, learning, monitoring news, and so on, in the above image, they’re all doing that while listening to music, handling business emails, checking their finances, playing games, communicating with the world via social media, some are using the phone as a visual aid, some as a means of payment, some as a convenient way of tracking their health and fitness.
If anything, modern technology is making humanity more involved. Especially now that politicians have twitter.
