21 November 2023: The science in Dr. STONE is indistinguishable from magic
Probably the last person who should have a gun.
When the series began, the science-based exploits described in Dr. STONE seemed somewhat plausible, at least for a show where everyone on the planet was petrified by a mysterious force and our protagonist measured the passage of time by counting in his head for thousands of years. Now in its third season (specifically, the second part of its third season), basically everything requires a similar sort of acceptance. It's not that the scientific principles are unsound, it's more that the viewer is required to ignore the engineering demands necessary to realize these designs, and the amount of time it should take to get stuff built.
Now would be a good time to break out some of that Jedi Mind Shit, Gen.
It's fine, though. Heroic achievements and overcoming incredible odds are very much a part of Dr. STONE, so I'm not bothered that everything gets constructed on time and works perfectly as intended, just as the superhuman physical feats that characters casually perform don't bother me.
We're never going to find out how the thing on her head survived thousands of years.
I don't actually know how much of the series remains. I think there are only five episodes left in the season, but I don't know if that means there are only five episodes left overall. In any case, the anime is still entertaining, and knowing that there will be an actual ending goes a long way towards reassuring viewers that the time invested in a lengthy series is worthwhile.
