@dmitryushakov has just published a summary of the yesterday's twitter discussion on direct modeling with @bcourter, @DeelipMenezes, and @SeanDotson. Dmitry himself also took part in that twittering.
My own comment. Yes, all those interested in spreading DM (not least - LEDAS), in one degree or another, can be grateful to Autodesk. However I think that it's prematurely to count how many millions of AutoCAD users will be infected by DM: rather probably the majority will not only stay noninvolved but for quite a long time will still not go beyond 2D. In addition, a specific approach of very popular Autodesk (a concrete Fusion, combination of DM with a "historical" method) may distort a trajectory towards complete victory of a true pure DM - with automatic detection of the design intent - an approach which, for example, LEDAS is developing. But these observations do not abolish or downgrade significance of the move just made by Autodesk, be it only marketing or not.
