I agree that everyone of that noteriety likely has a speechwriter(s). But the Dalai Lama's spoken words are considered sacrosanct by many, which does make this case a bit different. In a way, it would be like Jesus or Moses having speech writers. Which, they may very well have had. Your point about being appropriately translated etc is a good one.
True, and even if they didn't, they would if they were alive during present times. It was one thing to give a speech to hundreds or thousands of people live. It's another to have it recorded, aired on TV, youtube, linked, written about, published, etc. That kind of media infrastructure didn't exist then. The scrutiny of spoken word these days is higher than it's ever been, because it's not just a one-time speech. It's going to be recorded and published and broadcast, and around FOREVER. One misspeak and the internet will criticize anyone, even someone like the Dali Lama. Plus, he's pretty old. He's also not just a spokesperson and supreme being for his sect of Buddhism, he's also a political figure for the Tibetan people. So there's that too.it would be like Jesus or Moses having speech writers. Which, they may very well have had.
