I don't really think that that is where the money is anyway, though. I also don't really get the feeling many digital artists aim to have their pieces on someone's wall, at least. A lot of it is, I think, more commercial. Which I don't think is bad by the way, as it's the industry I want to get into as well. The digital art people have in their homes is usually product design. Cards, playing cards, mugs, plates, posters, phone or laptop casing, that sort of thing (not that all this is exclusive to digital artists, mind you).
Aside from that, most digital art stays digital. It never leaves the web or at least the screen. Concept art and promotional art for games isn't meant to be printed on a canvas. The only places that'll be seen in printed form is in related magazines, discussing an upcoming game. An even bigger chunk of concept art never even leaves the company for which it was created. It can be super creative and interesting, but it's simply not meant to be put on display but to serve the bigger picture (aside from being posted on some sites and someone's portfolio perhaps), so that the 3D modelers can work off of it.
Animation and comic design are also fields in which digital art plays a fairly large role, as well as illustration. Those fields have plenty of traditional artists as well, and they can co-exist just fine, but what I'm saying is; digital art often just does not has the same endgame traditional art has, and that's okay. We're talking very different fields of art here.
I myself would not want a canvas with a print of a digital piece on it as well, though a deck of cards with concept art from my favorite games would be hella rad, if you ask me, or a mug or T-shirt with a neat design on it. Or a poster. Once I have enough room on my walls again, the maps I got with some of my games will get a nice place on the wall.
But back to the opening post.
I'm not sure I'm willing to call digital art the absolute future of art. It will certainly play a massive role, without a doubt, but I also don't think traditional stuff will be out of the picture anytime soon. As I said in reaction to Dick as well; the art spectrum is so very broad that it's hard to predict where it'll go eventually. People keep finding ways to combine the new and the old, or to even just re-invent the new. With the internet it doesn't matter what kind of art you're into; there's a community full of like minded people just a few mouse-clicks away, and as long as that's the case, there will be room for a lot of different strokes for different folks.
You can't really replicate the average digital piece in your sketchbook, but you can also hardly replicate an oil painting on screen. Sure, you can add a texture layer, but you'll always see the difference between what needs to look 'painty' and what really is a scanned painting. Each medium brings it's own unique qualities to the table.
Neither was I very offended to find the digital art section under other. I do think lumping all sorts of digital art together has the potential of making the board a little messy, but I don't think it's a very crowded board, so it's not really a problem (sub-boards could be concept art, pixel art, photomanipulation if anyone here is into that sort of thing, vector art, 3D art etc.)
If things get really crowded, it can always be subdivided, I think. Having too many boards right off the bat makes the forum so long.
However, I wholeheartedly consider digital art art. Which is completely subjective of course, but I'm not really losing sleep over that. For me, commercial art can still very much be art. It takes a lot of creativity to be able to create a whole new world, with unique, well-rounded characters, an interesting plot and stunning visuals, wether we're talking comics, animations or games.
As has been said before; like any other artform, it requires time and practise. When it comes to it's difficulty in mastering in comparison to other forms of art I can't really say where it stands, but I can assure people that even after quite a few years, I'm still learning.
Because just as with watercolours, oil paint or acrylics, you need to understand color, balance and all the other things that come into play. Often enough someone who wants to get better will just buy some fancy ass tablet and then get frustrated when he/she doesn't automatically draw better than when they had a cheaper model. The tech is only as good as you make it. My tablet was one of the cheaper ones, yet works like a charm. The idea that the computer does all the work is ignorant at best.
If you don't understand anatomy on paper, you won't understand it on your screen either. If you can't look critically at your own work on a canvas, trying it digitally won't yield any better results.
And that's just me talking about 2D. 3D art is a whole nother can of worms. It might seem overly technical to some at first, but 3D too has a lot of potential. And again if you don't know much about anatomy, or architecture or color, with 3D, too, you will fall flat on your face.
A few digital pieces that I personally really like: https://epicturtles.files.wordpress....ceptart-07.jpg
This is concept art for Deus Ex: Human Revolution. It's goal here is to set the mood, to let us feel what that will be like in the actual game. And it does a splendid job in that. https://cdn0.artstation.com/p/assets...jpg?1434410230
Commission someone did for a book cover. With the lighting, I think the artist does a neat job of guiding the viewer's eye through the image, both with the light of the setting sun, as well as the lights near the castle and the bridge. https://cdn2.artstation.com/p/assets...jpg?1399579184
I believe this is just a fan art piece someone made for the Elder Scrolls V Skyrim. https://cdn1.artstation.com/p/assets...jpg?1454313826
3D art. Very often forgotten and underrepresented in arguments like these, but significant all the same. Pixar does a neat job with it as well. I love this piece because it's nicely unconventional as far as characters go. https://cdn0.artstation.com/p/assets...jpg?1400156118
And this one, this one I absolutely adore. She has something. They want it. If she lets go of the grenade, she takes it with her. But as long as she holds that grenade, they won't shoot, because then she'll let go as well and the bag will still be destroyed. That one item that has so much destructive capabilities, is also the only thing that maybe, just maybe, could save her. http://img12.deviantart.net/12db/i/2...iz-d6r3iqx.jpg
Again, a fair bit of storytelling going on here, lot of tension. But I really love the use of color as well. The green complements the creepy atmosphere. http://img14.deviantart.net/b475/i/2...ux-d4gvuep.jpg
Completely different style, but still neat. This would have worked very well with watercolours as well, though. https://s-media-cache-ak0.pinimg.com...011a93293d.jpg
3D piece. Nice use of warm-cold and I can only admire the patience and determination this must've taken.
