Software is the interface between man and the digital machine. Although software is as essential as data, there is much more attention for data management than for sustainable software. In the public policy domain the importance of keeping software alive is largely underestimated. This should change at our earliest possible convenience. The jump forward should be: a systematic approach to software sustainability combined with an international knowledge exchange infrastructure for software sustainability. Other actions regarding software sustainability involve the Software heritage Project and de Software Seal of Approval.
