As Art Moves From the Past to the Future It Becomes More Simplified as our Lives Becomes More Complicated

Almost as if to  calm down racing minds overloaded with such intense technology and little quiet time, futuristic art has become more simplified with greater open space on the canvas, fewer lines conveying emotion, and lighter paint, almost transparent as if to show ephemeral instead of solid,
to show things need not always be heavy at least while viewing art.
If we look at the first example we see da Vinci The Mona Lisa.
It is very dense, very elegant, very luxurious, and even though the emotion portrayed in the painting is calmness and serenity it is a heavy painting to view.
Our next example by Henri Matisse.
In his painting (I apologize for not knowing the title and being unable to find it) we see how passing years have already started lightening color and line. 
We are seeing openness and airiness in the art with the passing of years, as if as society becomes more complicated, our art becomes less so.
Now finally we see 21 century art by Mitro - "My Mom Pays More Attention to My Brother Than Me", where lines are kept to an absolute minimum. 
Where with only a few brushstrokes this incredibly simplified art is able to convey emotion so eloquently with minimal suggestion by painter.
This canvas is completely open letting the viewer fill in the painting with his own mind.
No done deal as earlier painting tended to be.
