Everyone 'here' fully groks to fullness the precariousness of, simply uncountable 'processes' in industries whose CIEIOs have a tendentious.. relationship to "what I.T. does", especially re. all the Hows? Bean counters, probably livid at the thought of supporting Two entirely unconnected systems--and equally ignorant of the manifold subtleties of what fully-[]- Separate means--would be the nemeses of the careful-enough architect of such a proposal, for all obvious pecuniary considerations in every corner-office. Is that even arguable?

Can 'one' [ever??] legislate some Musts? (given the odd little side-effect of maybe the Next ad hoc event? sorta leading to the chaotic demise of Westrun-civilization (or at least of: that Holy 'Progress' thing: which is worshipped quite more lavishly than any home-religion is, in any Rich country.))

Who wrote, The more we learn the darker it gets? Found only this re. torture. Mebbe so, on NPR.

As with AGW, Over-population [that which cannot even be discussed] and similar: this Elephant appears to get--even today--mostly lip-service and 'suggestions' that the devoutly-greedy "might deem to Make Happen." SUGGESTIONS? for a mondo-vulture-Capitalist to ... well. you. know. It's dirt snakes. Again and still.
