• They are changing our lives in ways both good and not so much.
• In the latter category, the way we use technology is making us more distracted and divided — and allowing bad players to create chaos and tear apart our open societies.

These dizzying creations may not be boosting the economy at nearly the same scale as prior big inventions.

• He argued that most of our genuinely impactful inventions were already with us by around 1970. That includes electricity, the airplane, air conditioning and the TV.
• Inventions since then, while impressive, simply are not of the same scale in terms of elevating overall productivity, Gordon said…”
