Just got out of a talk. The abstract of which promised some very exciting methods and results. They are also published in high-profile journals, so that added to the credibility. The talk was delivered in a horrible fashion. Small, publication size pictures that nobody at the back could read, even in the small conference room. The speakers style was very very car-salesman-y and less scientific. He was a Ph.D with several years experience from the industry, and perhaps asked for some of the hostility from the audience because of his style of talking. It was SO off-putting. Just greasy, hand-waving, grandiose-exuding. I must say, I have seen a lot of academics talk with similar grandiose hand-waving too, but minus the car-salesman part. In which one tries to foist their product on you, by giving vague answers to your questions and pointing out to some other unrelated plus point of the product when you ask about a certain deficiency. If this had been pegged as as a sales promotion, I wouldn't have minded so much, I would have got in with a different mindset. But it was pegged as a scientific talk. All questions raised in the audience were answered in a tangential vague way. Several people just took their cookies and coffee and walked out. I wish I did too. GAH.
I have also gone to other speakers from the industry who gave very balanced, scientific and insightful talks. So I don't want to paint them all with the same wide brush here. I'm just annoyed and want my hour back. When someone asks if your method can pick up small differences, and you say.."Only god can explain those small differences" I want to throw up. I just walked out at that point myself.
