A = 1

What significance does this number have? There are many references to it. https://en.m.wikipedia.org/wiki/42_(number)
Is it a reference to his 42 months of autocratic rulership over the world as the beast/antichrist?
This feels to be an important rabbit hole to investigate.

Additionally, Elon Musk is significant influenced by The Hitchhiker's Guide to the Galaxy, which he has spoken about many times

A group of hyper-intelligent pan-dimensional beings demand to learn the Answer to the Ultimate Question of Life, The Universe, and Everything from the supercomputer Deep Thought, specially built for this purpose. It takes Deep Thought 7+1⁄2 million years to compute and check the answer, which turns out to be 42. Deep Thought points out that the answer seems meaningless because the beings who instructed it never knew what the question was. When asked to produce the Ultimate Question, Deep Thought says that it cannot; however, it can help to design an even more powerful computer that can. This new computer will incorporate living beings into the "computational matrix" and will run for ten million years. The computer is revealed as being the planet Earth, with its pan-dimensional creators assuming the form of white lab mice to observe its running. https://en.m.wikipedia.org/wiki/Phrases_from_The_Hitchhiker%27s_Guide_to_the_Galaxy#
