That's an impression I got from reading the post (no time to watch the video). I also thought: Well, how many times do you get to suck before they think you don't belong there? Some ideas do need time to percolate and encapsulating them in a soundbite can lead to rejection without understanding the underlying depth. [This was previously posted elsewhere minutes ago due to a mis-click.]
I want to also add: My comment might be misinterpreted to think the person sucking is someone who's incompetent. That's not what I meant at all. But anyone can have a run of plain bad ideas before they strike gold. Or even silver.
