To those of us versed in science the word energy means something very specific and fundamental to the universe. Human-oriented monetary value is something entirely separate. “Digital energy” simply doesn’t exist, it is at best a metaphor, at worst it is incomprehensible nonsense. Saylor is an engineer and should know this which is why his insistence on repeating the term baffles me. My best guess is that he knows it’s just a figure of speech, but he uses it as though it’s actually true because he finds it resonates with non-sciencey folk.
