As a Brit, I've seen this cultural phenomenon in the UK too. Maybe I've just not been exposed to the right people, but "failure" is still a dirty word and it's rarely seen as a stepping stone to success.

Although I'm not all the way through it, I have a feeling this presentation was probably quite a shock to its live audience, and probably perceived as being quite tactless and impolite. I wonder what they actually thought of it and whether it effected any change in mindset.

Edit: I'm cringing all the way through this video. I'm not sure if it's a cringeworthy video or whether it's exposing my own fear of being embarrassed!
