This presentation uses three worlds, collective stance and learning
curves perspectives to analyze developments in human-computer interaction.
It argues from historic data that the human interests have remained unchanged
over at least five millennia, and may be expected to have the same basis during
the next millennium. It concludes that we are still at a very early stage in
the development of HCI, and that the major impact of the technology on our societies
is yet to come. To understand the issues involved we will need greater understanding
of the operation of our societies, their economies, politics and cultures, and
how these evolve under the influence of environmental factors including advances
in information technologies
