Have you ever noticed how some of the world's smartest people have a somewhat jerky stop-and-go speech pattern, sort-of like Google's autocomplete? It's not uncommon among smart people who are careful about what they say, strive for precision, and are cognizant and empathetic to potential contextual gaps among their audience and their different levels of understanding.

Elon Musk has a similar pattern, but it's not so much a speech disorder as it is their brain is working so fast, pulling from multiple sources and considering multiple perspectives. They're auto-editing their words in real-time, revising what they're saying while considering all of the above factors and more. But sometimes they get ahead of themselves and so in an effort to be clear and precise, they backtrack a few words and rephrase, filling-in as they anticipate potential contextual gaps. This is what you're seeing.

Rather than thinking they need to see a speech therapist, view it as a mark of authentic speech by someone who strives for precision and is empathetic to their audience. When you look at it this way, you can know and appreciate that you're witnessing the genuine workings of a brilliant mind.
