The recent partial collapse of the Metaverse, when Facebook parent company Meta lost 26% of its market value (or $232,000,000,000) in a single day, as well as the proliferation of new images this triggered of the ongoing transformation of Mark Zuckerberg’s flesh-and-blood body into a dead-eyed simulacrum of the sort only billions of dollars can buy, appearing ever more as if made out of the same materials as Stretch Armstrong (Karo corn syrup, latex), seemed a good occasion to revisit, perhaps more compellingly than on my previous attempts, the so-called “simulation argument”: the idea that what we think is reality is in fact a “computer simulation”.
