Even proper TED talks can have some big issues. I’m thinking specifically about Kary Mullis getting up on stage and saying anthropogenic climate change isn’t real because he found a study that says there’s a current that fluctuates and absorbs anything we do–or something to that effect. If you didn’t know anything about Kary Mullis and just heard “Nobel prize winner” you might assume he’s credible. In actuality he was a pariah for talking out his ass about things he doesn’t have expertise in and doesn’t understand, specifically his climate and HIV/AIDS denialism.
It’s always a good idea to approach any lecture with a critical view, but I can see why TED talks might warrant extra scrutiny. They project expertise and authority which may or may not actually be credible. The organization has a mottled record of vetting their speakers for actual expertise. (ETA: actual expertise in the content of their talk. Obviously Kary Mullis had actual expertise, just not in the things he said on stage)
Like many respondents on this decorporatized FOSS wang-dang-doodle, my answer is some variation on “Linux for desktop/laptop unless I’m forced to use the W-word” and “Whichever mobile OS makes the browser happen while I’m away from Linux, but I’m sad that it’s not Linux”.
