Friendship is the hardest thing in the world to explain.  It’s not something you learn in school.  But if you haven’t learned the meaning of friendship, you really haven’t learned anything.

Knowledge is not simply another commodity.  On the contrary.  Knowledge is never used up.  It increases by diffusion and grows by dispersion.

Fifty (50) years ago today, the first words were spoken by a human being on the moon (technically, in a vehicle on the moon’s surface).  The two astronauts were completing their landing maneuver checklist before speaking to Earth:
Buzz Adrin: Contact Light.
Neil Armstrong: Shutdown
Buzz Adrin: Okay.  Engine Stop.
Buzz Adrin: ACA out of Detent.
Neil Armstrong: Out of Detent.  Auto.
Buzz Adrin: Mode Control, both Auto.  Descent Engine Command Override, Off.  Engine Arm, Off.  413 is in.
Charles Duke
(at Mission Control in Houston):
We copy you down, Eagle.
Neil Armstrong: Engine arm is off.  Houston, Tranquility Base here.  The Eagle has landed.

The speed at which you walk, for example, can be eerily predictive of health status.  In a study of nearly 35,000 people aged 65 years or older in the Journal of the American Medical Association, those who walked at about 2.6 feet per second over a short distance — which would amount to a mile in about 33 minutes — were likely to hit their average life expectancy.  With every speed increase of around 4 inches per second, the chance of dying in the next decade fell by about 12 percent.  (Whenever I think about this study, I start walking faster.)

On the phone, I ask Li if she imagines there could have been a way to develop AI differently, without, perhaps, the problems we’ve seen so far.  “I think it’s hard to imagine,” she says.  “Scientific advances and innovation come really through generations of tedious work, trial and error.  It took a while for us to recognize such bias.  I only woke up six years ago and realized ‘Oh my God, we’re entering a crisis.’ ”
On Capitol Hill, Li said, “As a scientist, I’m humbled by how nascent the science of AI is.  It is the science of only 60 years.  Compared to classic sciences that are making human life better every day — physics, chemistry, biology — there’s a long, long way to go for AI to realize its potential to help people.”  She added, “With proper guidance AI will make life better.  But without it, the technology stands to widen the wealth divide even further, make tech even more exclusive, and reinforce biases we’ve spent generations trying to overcome.”  This is the time, Li would have us believe, between an invention and its impact.
