Looking at the list of available smells, I'm reminded that one of the positive side effects of smoking was that it deadened the sense of smell. It should go without saying that is a bad reason to adopt that addiction...

I miss smoking so much.

I really wish some things were real.

It would be neat to trade (nice) scents.

I'm curious to why "recording" and "playback" of scent/smell is still not mainstream as sight and sound.

Why is not a part of movies or games?

What are the limiting factors?

Scents are caused by numerous chemical compounds distilled in certain portions in the air.

In order to create a scent recorder, we'd need a machine that can detect every single one of those compounds at all possible concentrations; for a scent player we'd need a machine capable of forming those compounds at the proper concentration.

Turns out, it's much harder to do than record/emit photons or record/emit sound waves.

The limit is obviously sensors and output device technology.

Profit would be limited, hence little development.

They should make a 'dead Google product' smell, but then the stench might be overwhelming.

Google always makes me laugh on April 1!
