Google and Larry page committed to change the world

Many companies and CEOs claim that they want to
change the world, but Google and Larry Page seem to be
truly committed. Beyond Google's core business, Larry
Page has started projects to "cure" death (Calico), and
now we're hearing about Google Y (which is part of
Google 2.0) which has even more grand ideas to improve
the world.
Page reportedly wants to take on more long-term
projects, and with Google 2.0 wants to tackle the
biggest challenges facing humanity and how Google can
help overcome them. Calico is part of that initiative,
since death is probably one of the top "challenges" of
being human (if you see death that way). According to
The Information , Larry Page hasn't yet created the
Google Y research lab, but has proposed the idea.
Google Y would take on projects like creating a more
efficient airport, and even building a model city.
Those seem like pretty large scale ideas, but the plans
for Google 2.0 and the Y lab can get very small as well.
Page reportedly wants to get location tracking to be
precise "down to the inches." The idea appears to be to
create something like iBeacon, so you could identify
those close by, and get personalized service while
shopping. There are also plans for biometric security to
replace traditional passwords, but that is something that
has been on Page's mind for a while now.
It is incredibly impressive to see Larry Page attempting
to honestly change the world, especially since so far
he's been able to convince investors to let him work on
these projects that don't necessarily have traditional
business plans behind them.
