This has been a week for thinking about tech and consequences.

Let’s not spend time on that 53-word tweet by the US president.

The iPhone just turned 10! You might remember getting an early one. Whatever you had before became a paperweight. While Apple didn’t invent smartphones, it did revolutionize them. The items it replaced “could fill a warehouse of nostalgia,” notes a watch-worthy video at Recode. Some 1.2 billion iPhones have been sold to date, adding up to $738 billion in sales, reports Forbes.

Beyond ushering in the era of the ubiquitous smartphones, Apple also triggered an avalanche of apps. That undoubtedly helped speed our arrival at another tech milestone: This week Facebook reached 2 billion users worldwide. (Founder Mark Zuckerberg is bent on bringing the internet to parts of the world that remain disconnected.)

And operator behavior? Individuals haven’t always self-regulated very well. Bundled in with all of the good and productive, there is isolation, addiction, and bullying. States scramble to implement laws requiring hands-free phones for drivers. Families try to disinvite devices to dinner. Tweets own a weirdly big slice of the news cycle. (We said we wouldn’t go there.)

We’re seeing new signs of a quest for balance. One study indicates that nearly 6 in 10 teens now take voluntary breaks from social media (and are glad they did). That kind of milestone is worth noting, too. 

Now to our five stories for today.
