RISC vs. CISC in the post-RISC era

S. Casey writes "Ars Technica has a very cool article up that takes on the typical RISC versus CISC debate. The author argues that today's microprocessors aren't RISC or CISC, really, and covers the historical/technical reasons why these two distinctions aren't particularly useful anymore. It's pretty convincing (to me). " Essentially, the author argues that it is difficult, if not impossible, to have the normal debate because both chipsets have evolved features that used to be found in the other chipset.
