They have managed to nail computer vision, and the abilities of machines discern sounds and create speech are better than ever. Presently, the focus has been on the sense of touch – and the interfaces are focusing on the tactile, trying to refine it and give it the quantity (and at times quality) so that a machine may experience it the same way. But taste is what I want them to define next to a machine.
Computer Taste. Taste Recognition. As absurd as it sounds.
Vision and sound have probably been the easiest of sensory experiences for us to mechanize and digitize. Taste, I feel, shall probably be the last and the most difficult of all senses to replicate. Even with the most refined of present sensor-tech we have created that can detect and quantify a change in the natural world, taste is something at a higher level, it is a combination of the other senses. It is where the touch, smell and vision come into play together. Even with combinations of individual sensor-values affecting brain activity for each item tasted, what we would be able to create further from a model trained on this would only give us the brain activity equivalent, and it would not be replicating the sensation itself.
But maybe it will be possible one day, when the total sensory input gets strong enough to surpass taste, where taste is not necessary as a more powerful sensory dimension would exist in its place and be much more useful to an artificial super-intelligence. It would be like tasting one’s food by just by the sight or smell of it, like how we do countless times in passing.
That sensory dimension sounds a lot like desire.
The carcinogenic new car smell is often prized and romanticized, but we never mention the smell of old cars; part motor oil, part petrichor – the smell of the road and the trips it had been on. And now that too is a rarity to come across, because how the design of the vehicle-cabins has evolved.
In the years when cars did not ship at default with an air conditioner and all there was a fan, the body was not designed to seal the environment within the car from the elements, at least not in the same way as it is done today. And as the car would get older, the smell of the road crept in. The lack of comfort compared to the modern car could also be a sign of the machine being closer to its environment than it is now, distant from our range of comforts yet more truthful to what it was and which soaked in everything it had gone through. In these cars, just by the mere smell, one could accurately guess where they had been parked and whether people took care of them or not, or even whether they drove them too much or too little. Car fresheners would also ride the strong foundation of these natural smells, unlike today where they just hit you in the face with the sweaty smell of a closed air conditioned chamber. The only thing I can accurately guess in the modern car is whether someone ate an EggMcMuffin in it in the past two days. And maybe there is a hint of this old car smell on an old public bus, but it still lacks the personal character and lies in public space and use.
But hey, now we are far from that, cars are not cars anymore – just electric carts which you would not even have to drive in a few years. But blessed would be those who saw the automobile at its most raw – a man made machine which was very much a part of its environment, with its own unique smell. Among the various descriptable and undescriptable, tangible and intangible feelings of driving and owning a car, the smell will also be something we will miss when we entirely stop driving as a society.
