  One of the wow moments is the
day you remember how
much you now depend on
your phone,
  which is the day you lose it
  right?
  Another one is the day when you
put your whole genome in the
cloud, and then you realise
that researchers are going to start
using your genetics, with
your permission, right, to help
other people with these extraordinarily
difficult diseases that people get
For me, last week
I met a blind man who could
now see because
he had a retinal implant, and
he told me, 'I can see with
my eyes closed.' That's what
did it.
  It's extraordinary.
  So the underlying technological
things going on here have to do with
machine learning, and Andrew mentioned
this a little bit. What machine learning is
is a series of what are called neural
networks, and they're layered, and
you take these layers and you classify
at various levels what you see
These algorithms work by taking a
very large amount of data and producing
  new algorithms, essentially, and
they get better with more training
data. This works for
lots of business things that you see
but it doesn't work for things which have
very narrow or specialised
data, or very infrequent data. So
I'll give you a simple example
It works well for consumer
fashion, but not very well
for luxury fashion
because there is so much more consumer data
than there is luxury data. So
easy to understand that the way
this technology will appear
in our lives, in things where there
are lots and lots of data sets
I mentioned driving a car
There's lots of data driving a car
because there are lots of things going on all the time
Plus, we've driven our cars
you know, half a million miles, whatever
the number is, and every time you drive
the algorithm just gets a little
bit better.
  So there are all sorts of questions you
could ask. 'Which stores should have my
inventory?' 'Where will the traffic
be?' A possible future could
be, 'Suggest what I should
do today.' I mentioned we're trying to move
to suggest. Maybe we'll be able to
do that. 'Send me a summary
of something.' 'Make me smarter
on a subject I know very little
about. Educate me.' Right? That's
the kind of thing that these things can do
