Clearly, Albert Einstein would have been a good speaker at a TED Talk. He was one of the most brilliant scientific minds of all time, and he could have spoken on any number of scientific subjects. Although some of his philosophies may not have been true, he could still be a good speaker.
There is no way someone today can speak on someone living in another area. He added many great things to the science world. He made many advances and breakthroughs no one else at that time was even considering. They actually thought him insane because of his thinking. He was ahead of his time.
So many people, throughout history, have tried to make a name for themselves by being provocative. One of the most popular ways to be provocative is to try and disprove the supposedly great minds that came before you, something that has only increased in today's post-modernist academic environment, and will likely continue.
I do not agree with the TED letter on pseudo science that claims Einstein would not have been eligible to give a TED talk. He claimed that Einstein theories were bad science with which I disagree. Einstein was considered a genius for a reason and most of his theories led to science today.
The TED letter in question didn't specifically mention Einstein. Another TED user brought up Einstein. The letter bans "bad science" in which people tout the benefits of genetically modified foods. "Bad science" means scientists who have been discredited by their peers. The TED poster who originally mentioned Einstein says he and his peers were ridiculed by mainstream science when the theory of relativity first came out. "Bad science" shouldn't be labeled as such--just because science can't prove certain aspects of society it doesn't mean certain subjects are "bad."
