Can a smart screen ever replace the texture and grade of real colour on paper?

I made this on an app by Wacom called Bamboo paper. I saw the watermark of the app on a Facebook friend's artwork and i immediately headed to the Play Store to download it. Within the next New York minute - because that is how fast our world is constantly trying to be - I was fingering my phone, awestruck and ogling at the emergence of on-the-go digital technology for my on-the-go artistic endeavours.

It was a very attractive experience, doodling on this - even if i was short of in-app purchases like brush pens and even though I was missing a pressure-sensitive, bluetooth connected stylus. I experienced immense gratification. But just like my interaction with every other piece of digital technology, i hit a speed bump in my frame of mind. An odd something which needed further investigation. I thought to myself about this...sense of satisfaction - a very deep-rooted, simple feeling of completion of something. A feeling of having taken a tour to my soul and come back letting out a very heartfelt 'ah' from my windpipe.

I missed that hardcore, grounded feeling of achieving an effect or stroke by hand, by spontaneously varying the pressure of a sketch pen or a highlighter on creamy white paper. I missed the feeling of a permanence flowing through my bones, mingling with my soul and gripping my ribs with a conscious power that no AI form could ever give.

On real paper, there have never been any glitches, lags or magnifications. There are no save, undo or redo functions. There is no need of palm rejection software. There is just one candid relationship between the artist, the tool and the canvas.

For all their multi-fold purposefulness, their dual-natured utility, smart screens lack one thing that I cannot help but feel. 
I cannot eat digital art.
