Things are changing so fast I think its pointless to

problems that won't occur for 80 years, it would be like demanding  the
Wright Brothers
solve the problem of congested airports before they built their first

​Well sure but you almost make that sound like a bad thing; it involves
science and Dyson spheres are fiction because they don't exist, at least
not yet.  ​

​I think we've done rather well at solving problems, read Steven Pinker's "
The Better Angels of Our Nature
eople love to complain about how bad things are but the facts are that
right now humans are killing each other at a far lower rate than any other
time in history, and they live longer and are better educated.​too.

​Life likes warmth. I​
n the last billion years it has never been warmer than during the
Carboniferous Era 360 million years ago,
​and there has never been more living stuff per square foot on the planet
then ​

Entropy isn't always the enemy. Maximum information
, or at least maximum
​information that intelligence finds ​
 seem to be about
midway between maximum and minimum
entropy. Put some cream in a glass coffee cup and then very carefully put
some coffee on top of it. For a short time the 2 fluids will remain
segregated and the
entropy will be low and the information needed to describe it would be low
too, but then tendrils of cream will start to move into the coffee and all
sorts of spirals and other complex
​and pretty ​
patterns will form, the entropy is higher now and the information needed to
describe it is higher
​ too​
, but after that the fluid in the cup will reach a dull uniform color that
is darker than coffee but lighter than cream, the entropy has reached a
maximum but it would take less
​interesting ​
information to describe it.

Another example is smoke from a cigarette in a room with no air currents,
it starts out as a simple smooth laminar flow but then turbulence kicks in
and very complex patterns form, and after that it diffuses into uniform
​and very dull ​

​I like the fact that entropy increases, if we ever get to the point where
that doesn't happen anymore that would mean the universe has reached heat
death. ​
