Any scientist will tell you that science is made possible by its instruments. Now the humanities have a new instrument. Masses of data, that previously was manually unmanageable, can be collected and processed. This is a boon to many humanist fields. It also means that technical fields can share some research methodology with the humanities.
Accessible data makes experiments reproducible.
It lets one researcher use the same data to explore a competing hypothesis. My daughter is a historian. She tells me that historians always look back in time. If you believe as I do that some of tomorrow's projects will require close and deep collaboration of humanists and technical folks, then the fact that the computer is a powerful tool for the humanists will help cement the relationship. For issues where computers are used, their methods of experimentation and exploration will be common.
