I have got the same feeling. It is this idea of moving away from the pencil-and-paper operating system for modeling complex systems. Victor is more about making computing explorable and accessible to the masses, whereas Sussman is more about figuring out new ways to compute things. However, both are basically arguing that our current abstractions are not enough anymore. That is, we need to revisit some of the assumptions that were made 40 years ago about how programs should be structured.
