I watch quite a few tech talks (via Youtube, mostly conferences), mostly to familiarize myself with concepts, and tbh I rarely have issues being "bored" by talks like the ones described as boring in this post.
I get bored, however, by fluffy talks that have lots of memes and pictures and big text and anecdotes. In any reasonably complex actual tech talk, you'll have concepts that need slides with a bit of text and maybe even formula (or code), simply because the audience will sometimes get distracted or forget what you said a minute ago. I find that perfectly fine and better than the alternative.
So overall this seems to be advice for people who wish their tech talks were actually TED talks.
