Blah, blah, blah... I feel like I've been click-baited. He constantly hypes us on how important it will be, but doesn't explain what it actually is - not even remotely.

At 04:50 he says that scent is different from sound and light which they have been digitized because they are energy while scent is mass. So how did they solve scent/mass problem???
Digitizing sound is analyzing the electrical signal we get from the movement of a speaker and analyzing into single frequences that can be then reproduced electronically.
Digitizing light I guess means having sensors that can transform light into electrical signals and then revert that process to reproduce the same light.

Generally digitizing means expressing a number with only a finite number of binary digits or expressing a physical quantity as an electrical signal. But for that process to be useful (and brag about it) we somehow must have a way to reproduce the digitized quantity to get signals similar to the non-digitized form, using electronics.
SO,
-HOW DO THEY DO IT WITH SCENT? HOW DO THEY DIGITIZE A SCENT?
-WHAT SIGNAL IS BEING DIGITIZED WITH THE SCENT? IS IT OUR NERVOUS-RESPONSE TO A SPECIFIC SMELL? IS IT SOME ARTIFICIAL SCENT-SENSOR
-HOW CAN WE CREATE A SYNTHETIC SMELL FROM A DIGITIZED ONE?
-CAN WE SMELL THAT DIGITIZED SCENT? IS IT LIKE AN AIR-FRESHENER?

WHAT THE HECK IS IT?... We'll never know...
