I think of writing for you people
however far removed.

As you harness nuclear fusion 
for an abundance of clean energy,
all that came before- call primitive.

And maintain the Earth's population
at an optimum level. An issue
never before properly addressed.

These two achievements are the wings
to allow a sensible view for the first time,
carried free of age old labyrinths.

You may double the average life-span. 
Time is all that can really be owned,
and sharing it well is its great value.

You may find Life thrives among the stars,
and messages left to benefit far worlds
mark a leap in cosmic evolution.

I think of a million years collapsing,
an illusion at last found out,
reality moving close as it might.

And I bank on your return to Music.
Recognising the most obvious exemplar
of harmony and its power for good.

Again, the past loiters at your gate,
a beggar,  hawker,  canvaser,
ready to converse the day away.

And minds so drawn to the conversation
feel as close to their correspondents
as to the people here on the train.
