Can smell be captured like a photograph?

We can take pictures to freeze a memory at a single instant in time. We use a camera for that purpose. But memories aren't just made up of lights and colours, they consist of smell and tactile sensation too. How come there isn't a device to capture the smell at any particular instance? Or the warmth of the sunlight hitting your face? Or the gentle caressing of the breeze that tussles your hair?

I guess that's why looking at pictures feels like the copy of a copy to me. It's like eating aspartame - your tastebud feels the sweetness but it is ultimately empty in calories.

There are a few things in the future that I'm looking out for:


1) A transparent metallic material

I'm in the market looking for a water bottle, but whenever my wife asks me what sort of water bottle I'm looking out for, I'll reply it must be made of metal (so that it's more durable and doesn't have chemicals leaking into the water) and transparent (so that I can know how much water is left). I'm still searching for one, so let me know if you know one lol

2) A device that can change the size of things

Whenever I'm tired of walking in the shopping centre, I told my wife to shrink me and put me into her pocket and carry me around. I guess the device can also be used to shrink a car and save everyone more land space instead of building car parks. I'll be willing to buy such a device.

3) A 'camera' take captures smell

Imagine taking a picture of the sea, and looking at the pictures will immediately trigger smells of the salty breeze. The best I can think of are those scratch-and-sniff stickers, that is said to take over the gaming world (imagine in a first-person shooter game, you walk in a sewer so you scratch a sewer sticker and sniff it for the atmospheric immersive experience) but ultimately became as extinct as a technological dodo. That'll be something to look forward to.

I'm sure in the 1800s, there'll be someone wishing for a list of things like these too. And when it happens, a lot of the old ways of doing things are disrupted. Gone like the buggy whips companies used for horse carriages. If I can imagine this wishlist, I'm sure it'll become a reality one day. Perhaps not in my lifetime but it'll be possible in somebody's lifetime.

Are there any investments now that you have that are on the cusps of extinction? The closest one that I have is perhaps Singtel. We all say that the fall in price for Singtel is due to the competition locally and worldwide...but what if it's the beginning of the fall of traditional telco business? How about banks? Will banks be obsolete in the future? Is there truly any business that you can guarantee that will stand the test of time?

I can't answer that, hence I will invest accordingly to my lack of knowledge. I will never be able to concentrate my stock holdings, and can never be able to sleep well with just 8 stocks in my pocket. This company might be so good and I'll whack 80% of my networth inside? Some people might be able to do so, but I'm quite sure I'm not one of them.
