We have invented devices to record what we can see, and devices to record what we can hear.
Why haven’t we invented something to record what we can smell?
How would this work if we did?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

You see via light and hear via sound. Light and sound can be easily recreated by machines because they are both non-material phenomena.
Smell is caused by specific chemicals in the air that would have to be released to recreate it.
