The times of a lone artist toiling away for a rich patron is dated.
Today there are so many more ways to be an artist. Through technology artists can be community leaders, social activists, brands, public speakers and so much more.
I think if anything that artists today have a duty to do more than just create artwork, to create outside of their primary practice - we have such a great oppertunity that it'd be a waste not to use it.
These creations outside the studio then feed back in to the ones within it, creating better art which then reaches more or affects deeper - in return fueling more proactive oppertunities for the modern artist.
