'Context switching is the mind-killer': Elon Musk shared a strange, altered quot...

• Elon Musk has three times shared an altered version of a famous quote from sci-fi classic "Dune."

• "Fear is not the mind-killer, context-switching is the mind-killer," Musk tweeted Wednesday.

• The quote seemingly means that constantly switching focus is mind-numbing.

Elon Musk once again posted a bizarre altered clip from the 1984 sci-fi movie "Dune" in an apparent reference to his extremely hectic work schedule.

The nine-second clip, which Musk posted in the early hours of Wednesday morning, shows a scene from the movie featuring actors Siân Phillips and Kyle MacLachlan, with altered subtitles overlaid.

The text over the clip reads: "Fear is not the mind-killer. Context switching is the mind-killer," altering the words of a famous passage from the sci-fi series: "Fear is not the mind-killer."

Musk's post was captioned: "Oh, you know, keeping busy …"

Musk has repeated the edited quote before in an identical tweet in 2021, and again in a Clubhouse chat. Musk's altered quote is taken to mean that switching tasks and contexts repeatedly can be mind-numbing, while maintaining focus on one task is the real winner.

The billionaire CEO is currently juggling the leadership of five companies, including Twitter, where he has enacted a sweeping series of staff cuts and workflow changes in just six weeks.

His four other businesses include Tesla, the electric vehicle manufacturer; aerospace company SpaceX; a neurotechnology firm called Neuralink; and The Boring Company, a tunnel construction startup.

The original quote altered by Musk comes from the so-called "Litany against Fear," a text that makes up part of Frank Herbert's 1965 science fiction novel "Dune," on which the 1984 movie is based.

The original quote is: "I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain."
