Answer 1

Smelling is potentially a matter of life or death, so our sense of smell is much more sophisticated than our sense of sight. Sight is based on detecting just a couple of wavelengths, so we can reproduce pictures pretty easily. Our sense of smell can detect thousands of different combinations of chemicals. so try to reproduce it is hard.
