We've got Mill team members in this thread, but anyway here's the short, short version: It's about using as much of the die area on the CPU chip for actual computation, rather than supporting an instruction set with outdated design. The programmer's model of computation today has little correspondence to the realities of current semiconductor process technology in terms of what's fast, and what's easy to implement in hardware. The Mill is a bottom-up redesign that takes into account many of the design constraints with current technology, and attempts to design a good architecture that can maximize actual computational throughput.
