Elon Musk has named his new language model Grok. The word comes from the science fiction novel “Stranger in a Strange Land” (1961) by Robert A. Heinlein. This famous novel features two characters who have studied the word. Valentine Michael Smith (aka Michael Smith or “Mike”, the “Man from Mars”) is the main character. He is a human who was born on Mars. Dr “Stinky” Mahmoud is a semanticist. After Mike, he is the second person who speaks the Martian language but does not “grok” it. In one passage, Mahmoud explains to Mike: “‘Grok’ means ‘identically equal.’ The human cliché. ‘This hurts me worse than it does you’ has a Martian flavor. The Martians seem to know instinctively what we learned painfully from modern physics, that observer interacts with observed through the process of observation. ‘Grok’ means to understand so thoroughly that the observer becomes a part of the observed – to merge, blend, intermarry, lose identity in group experience. It means almost everything that we mean by religion, philosophy, and science – and it means as little to us as color means to a blind man.” Mike says a little later in the dialog: “God groks.” In another place, there is a similar statement: “… all that groks is God …”. In a way, this fits in with what is written on the website of Elon Musk’s AI start-up: “The goal of xAI is to understand the true nature of the universe.” The only question is whether this goal will remain science fiction or become reality.
