Why are all the speakers at tech conferences so bad? And why do good presenters get invited to every conference on the planet?

Public speaking is a skill. It takes work and practice. Most tech folks have neither the time nor desire to do so.

It's copycat behavior. They are imitating other presentations.

Who does? The bad one's or the good one's? Genuine question.

Both.

The good ones snarf ideas from other good presenters when they see something useful.

A lot of bad ones imitate other presentations as the "minimum standard" because creating a good speech takes a LOT of work.

I'm also going to point out that a lot of tech speakers aren't native speakers of English. If you made me, a native English speaker, give a presentation in French or Chinese, I'm guaranteed to be a bad speaker.
