Amy Goodchild published a comprehensive primer on the emergence of computer art in the 1950s and 60s. It is inspiring to see the depth of what artists were able to create using primitive, inaccessible, and expensive technologies compared to what is available today.
Artists have a long history of pushing the boundaries of what is possible. In recent years, the space of possibilities has expanded dramatically. I hope there are creative pioneers working today to push us even further.
