what kinds of things do you think we'll be able to do by mid century?

[misterlucky_2000]

the last century was kinda like a growth spurt in human development. we went from horse and buggy, to cars, planes, rockets, radio, and television. ..from riding cross country on horseback and locomotive, to flying around the world at supersonic speed and space travel. Digital cameras, cellphones, plastic surgery, plastic , sky scrapers, tv, million dollar salaries..
what do you think this century will bring us? what's the next big thing?
