@Brandon9000,
Quote:The universe is about 14 billion years old. Humans of today could crush humans from 100 years ago. The chances of a random encounter bringing together species so precisely at the same level that a fight would be meaningful are small.
This is a naive assumption. When Caesar conquered Transalpine Gaul, the Celts were physically larger than his men, they were better fed over their lifetimes than his men, they were fighting on their own home ground, and their metallurgy was at least one century, if not two or three centuries in advance of the Romans. Caesar handed them their collective military ass because of Roman social organization.
By the same token, an Araucanian Indian tribe of South America, the Mapuche, who inhabit Chile, turned back an "Inca" invasion about a century or more before the Spanish arrived. They very nearly exterminated the first Spanish settlers, and fought them to a standstill for, literally, more than two and a half centuries. After O'Higgins and Marti liberated Chile, they continued to successfully fight off the now Chilean settlers. In the mid-19th century, the government, at public expense, provided firearms and ammunition to the settlers. The Mapuche were pushed back, to an area of less than 20% of their ancestral lands. The Mapuche survive to this day. The were technologically inferior to all of their enemies, and their social organization was inferior to that of the "Incas" and the Spaniard.
It is always naive to assume that technological differences are as significant as you seem to claim, and that they axiomatically confer any particular military advantage. I find your thinking on this matter to be two dimensional, and your assumptions both about how far technology can progress, and what the likely significance of any difference would be to be a product of speculation, rather than certain knowledge.
