Since modern art is about 100 years old now, technology didn't have much to do w/ it. You can give someone all the technology in the world, but if they don't have a unique vision and talent, along with discipline and drive, it isn't going to help them. Anyone that thinks that "anyone can do it" doesn't know very much, but that's OK. That's how most people are. Asleep at the wheel. Anyone can copy an original, existing idea.
There's the critics, and then there's the people who create the works. Nothing has changed since cave art. I'm sure some Cro Magnum guy groused "Hmph, he thinks he's something. Why, anyone could do that". Talk is cheap. Artists talk w/ their works, not their mouths.
