Keller Jordan Posts Theorem on Computational Singularity Duration

Keller Jordan, a research engineer, posted on X a theorem stating the maximum possible duration of the computational singularity is 470 years. The post includes a proof comparing the estimated FLOPs capacity of all computers in 1986, at most 4.5e14 according to Hilbert et al. 2011, to at least 1e22 FLOPs today based on public Nvidia revenue and GPU specs. The tweet presents this as a calculation of an upper bound on singularity length.
