Here we are at TED, and all the time we are very conscious of the huge challenges that human society has right now -- curing cancer, understanding the brain for Alzheimer's, understanding the economy to make it a little bit more stable, understanding how the world works.
Kita berada di TED,  selama ini kita sedar tentang cabaran-cabaran besar manusia: Merawat kanser,  memahami otak pesakit Alzheimer, memahami ekonomi untuk  menjadikannya lebih stabil, memahami bagaimana dunia berfungsi.
