Doesn't the funnel metaphor imply that all people come to the end, just not at the same time?

What they are talking about seems more like a sieve to me.

The sales funnel has been commons sales parlance for decades, its not new.

Most of the stuff he talked about is not new(most established companies do it), he just put it all together on a simple guide.

Just out of curiousity, what is the ideal format for this type of "simple guide" ?

I see, thank you.
