The way methodologies like BEM and SMACSS work is to acknowledge that the cascade never works to your advantage, and avoid it entirely.

The methodology gives you the tools to have control over the cascade. You cannot avoid it entirely.

Edit: Also the point I was getting at was that cascade is a useful and powerful tool, just as the methodologies for controlling it are. We will also soon have a property that will eliminate the cascade entirely... all:unset;

I just think the problems and solutions listed in the talk are either non-problems or are things that could be solved in superior ways. And that it introduces more problems and limitations than it solves.
