Jack,
Hybrid technologies are indeed the way forward, but as in biology, the number of kinds of hybrids is limitless. Simplest and most general solution: Support all and any kind of hybrid in a very general foundation.
Jack: he anchors his architecture in SemWeb technology, which is not on my critical path.
Tim B-L's 2000 proposal for the Semantic Web was very powerful and general. Unfortunately, it got hijacked by the decidability gang. What came out in 2005 was a weak version of what could have been far more valuable.
Arun Majumdar and I were both working on the IKRIS project, and our VivoMind and Permion companies built on what could have and should have been the product of a truly innovative Semantic Web project.
Two things killed it: (1) the decidability gang, and (2) a funding cut by Congress in 2006.
John
PS: I am totally horrified by the current slash and burn cuts. They're saving millions of $$$ by cutting projects that are worth billions -- or trillions in the long run.
All our Internet and satellite communications today are based on a wild idea that somebody might have killed to save a few bucks. Nobody knows what has been killed in just the past few months.
