 From what I've read, that seems to be their intent. In this over-hyped world, I think D & D showed real guts advocating caution the way they do (even though they don't preclude further advances). Although they aren't implementors, they have planted a stake of a kind that is rare in IT, being so well-grounded compared to all the adhoc products that have so little theory behind them (IT "practices" outside of database have also been eschewing theory for some years.) I suspect that even if TTM doesn't instigate a notable version of "Tutorial D", it will lead to a few take-offs or variations that stick to first principles and advance the field as well. The first places I'd predict this happening would be outside the traditional western business process ideologies and their disrespect for theory. That would probably rule out North America and much of Europe and maybe conventional machinery as well as traditional applications. Too much ignorance, market concentration, power-brokering and pig-headedness in the vested interests of conventional IT. Igorance in government too, as most of the western ones who claim to be so tech-savvy can't see the insidious dumbing-down effects of such software concentration. If it doesn't look Standard Oil's supply and distribution monopolies of a hundred years ago, it can't be a problem. And the western governments wonder at the same time why they are losing their influence.

I know that's a pretty grand indictment, but i just got a new keyboard and couldn't resist.
