The Future In The Present

Science fiction is largely about the impact of the future:

the Time Traveler passes through tomorrow and into futurity;

Wells' and Stapledon's future histories begin by analyzing their present, then continue the story;

Poul Anderson's first sf novel, Brain Wave, begins with a contemporary setting but then the world is transformed;

as Brian Aldiss commented, James Blish's "Beep"/The Quincunx Of Time really is about the future (see The Dirac Transmitter);

when the President of the Parliament of Man on Avalon complains that the military would build bases in the fourth dimension against invasion from the future, the First Marchwarden of the Lauran System retorts that the future is always invading (see here);

in A Midsummer Tempest, xxiii, Roundhead hot-air balloons hang above Cavalier-occupied Glastonbury Tor "...like the future itself." (p. 208)
