The last time a human set the world record for solving a Rubik's Cube, it was Max Park, at 3.13 seconds for a standard 3×3×3 cube, set in June 2023. It is going to be very difficult for any human to pull off a John Henry-like usurping of the new machine record, which is more than 10 times faster, at 0.305 seconds. That's within the accepted time frame for human eye blinking, which averages out to one-third of a second.

TOKUFASTbot, built by Mitsubishi Electric, can actually pull off a solve in as little as 0.204 seconds on video, but not when Guinness World Records judges were measuring. The previous mechanical record was 0.38 seconds.

There are a few footnotes and caveats to what would otherwise be an incremental gain and nifty slow-motion video. The first thing is that the world record reported is for "fastest robot to solve a rotating puzzle cube." That intriguingly sidesteps the much better-known "Rubik's Cube" identifier. Rubik's notably lost its trademark on any rotating 3×3×3 cube puzzle game in Europe. Perhaps Mitsubishi and Guinness simply wished to avoid touching a trademark registered to a company with a known litigation history.
