The audience is also able to detect professional speakers like yourself, with calculated hand movements and inauthentic voice pitch calibration and is equally turned off -- its just that professional speakers so rarely admit that since they make money off saying otherwise. The problem here is just that the topics aren't compelling enough. And you rarely get a good speaker who also knows the topic well so as to be perceived as authentic.

Look at Elon's keynotes, they are TERRIBLE from a public speaking perspective, but excellent content that generally is interesting. Also no one perceives them as inauthentic, just off-hand-ish. It works.

> inauthentic voice pitch

That would be a "wannabe" professional speaker, not an actual one, imho.

Sure. No true Scotsman and all.

the pros are cheesy as hell.
