The development of art is inextricably linked to the advancement of technology. From early cave paintings to Renaissance paintings, artists have continually developed new tools and techniques to realize their creative visions. Today, in the age of the digital revolution, we are experiencing a new form of art production in which machines, especially artificial intelligence (AI), play a significant role. In particular, digital brushstrokes - the way machines create works of art - are opening up completely new perspectives in the aesthetics of art.
