but if Frankenstein isn’t sci-fi then nothing I’ve seen labeled as sci-fi is.
And my point is if Frankenstein is scifi, then so is earlier stuff...
It's all where you draw the line, some people draw that line where electricity is involved, because electricity was a pretty big deal.
Earlier stories have more primitive science, later stories have more futuristic science.
In the 2nd century some guy wrote about travelling to the moon...
Where he found Moon people who were at war with the sun people.
By your definition, isn't that also SciFi?
