In this paper we review the current state of the problem solving environmen
t (PSE) field and make projections for the future. First we describe the co
mputing context, the definition of a PSE and the goals of a PSE. The state-
of-the-art is summarized along with the principal components and paradigms
for building PSEs. The discussion of the future is given in three parts: fu
ture trends, scenarios for 2010/2025, and research issues to be addressed.
