INTO
THE
FUTURE
Culture
Background
Analysis
What
will
the
city
of
the
future
be
like?
No
one
knows
for
sure,and
making
predictions
is
a
risky
business. But
one
thing
is
certain
about
the
future
city—they
are
going
to
get
bigger
be-
fore
they
get
smaller.
Here
are
some
of
the
ide-
as
for
running
a
city
of
50 000
people
in
the
year
2025.
(1)To
get
rid
of
garbage
problems,the
city
will
load
huge
spaceships
with
waste
materials
and
send
them
towards
the
sun,preventing
land-
fill
and
environmental
problems.
(2) No
smoking
will
be
allowed
within
a
future
citys
limits.
(3)In
the
future
all
shopping
will
be
done
online,and
catalogues
will
have
voice
commands
to
place
orders.
( 4 ) Everyone
will
be
given
a
telephone
number
at
birth
that
will
never
change
no
matter
where
they
live.
(5) All
forms
of
recreation,such
as
cine-
mas,bowling,concerts
and
others, will
be
pro-
vided
free
of
charge
by
the
city.
(6)All
cars
will
be
powered
by
electricity,
solar
energy
or
wind,and
it
will
be
possible
to
change
the
color
of
cars
at
the
flick
of
a
switch.
(7) Distance
surgery
will
become
common
as
doctors
carry
out
operations
from
thousands
of
miles
away,with
each
city
having
its
own
tele-
surgery
outpatient
clinic.
(8)Old
people
and
people
with
disabilities
will
be
able
to
go
anywhere
in
the
world
using
high-tech
cameras
attached
to
their
heads.
(9)Traveling
in
space
by
ordinary
citizens
will
be
common.
Each
city
will
have
its
own
spaceport.
