Honestly, I would be happy to see a podcast / Youtube series come out that finds quality tech talk speakers, and polishes them up to TED level: concise 20 minute videos, with top notch audio, well rehearsed presenters and informative content.
Destroy all software is closer, but is kind of like one guy. Great for him! And for me on my flight here in a few minutes. But what I envision is more like training speakers to be concise and engaging yet informative. Kinda like how an editor helps a writer cut out things to make a better novel, but for tech talks. A tall order, I know.
