There seems to be an implicit idea here that being a persuader is a bad thing.
But even the informer is persuading people of something.
After all, to communicate at all, you MUST induce some sort of state transition in the recipient's brain.
And both the informers and the persuaders in your presentation are attempting to induce such a state transition; they differ only in what state they're attempting to induce, who they're trying to induce it in, or how effective they're willing to be at inducing that transition.
If the informer is uncertain and wishes to con...
You can't just be "intelligent over and over", because discovery and insight are essentially random processes. You can't just find insight, you have to look for it, in the same way that evolution searches the option space.
Yes, you can always have better heuristics or search algorithms. But those heuristics are not themselves intelligence. And there are always new heuristics to discover...
So, I don't think mere insight into the process of intelligence would allow you to be bored, since the things to be discovered by intelligence would still be ...
It is important to note that while emotions are triggered by relative perceptions, they are not themselves relative -- and what they are triggered by can be changed.

It's not a one-way street; with proper technique (e.g. NLP anchoring and reframing methods, to name just a couple) you can change the cached "meaning" of a certain class of events so that they have pretty much any emotional content you choose.
Granted, my personal experiences run in the direction of modifying "negative" things to be positive, and I haven't had much call for keeping around any negative feelings.
Truth is, your concern about losing the negative feelings is irrational... probably based on a science fictional ideal of "...
Hm. I wonder if you acquired any other implicit assumptions from superhero ideals. Like some of the ones that I found in myself, and described here: Everything I Needed To Know About Life, I Learned From Supervillains. For example, might you have acquired a bias towards doing the "impossible"? I know I did.
