The article of record as published may be found at http://dx.doi.org/10.1145/1880066.1880067The standard reference model for computation, the Turing machine, is a powerful model for digital computers and it can simulate every other computation model ever proposed. Yet the Turing machine information process -- execution sequences of machine configurations -- is not as well matched for the natural, interactive, and continuous information processes frequently encountered today. Other models more closely match the information processes involved and give better predictions of running time and space. Peter J. Denning organized a symposium of leading thinkers to explore this question.

Denning, Peter J.; Wegner, Peter (ACM, 2012-07-01);What is computation? This has always been the most fundamental question of our field. In the 1930s, as the field was starting, the answer was that computation was the action of people who operated calculator machines. ...
