>>95958187After the fall of humanity, other human populated planets survived for *thousands of years* before the Emperor got the Great Crusade off of the ground, and developed their own civilizations. Hell, there are STILL new planets that are being discovered and introduced to the Imperium of man, and thats another 10,000 years on top.
If surviving for over twice the length of human recorded history, by yourself, in the 40k galaxy is 'a slow crawl towards extinction', then it must be a VERY fucking slow crawl. And hell, some of those other human civilizations had better tech than the IoM, or were expanding and carving out their own little empires before the Great Crusade broke them. Without the Emperor's involvement, ANY ONE of those could have gone on to found a new human galactic civilization, or more likely multiple competing ones, and THOSE wouldn't have been hamstrung by the AdMech, the Imperial Creed, or having gifted Chaos an immortal army of supersoliders.
The Emperor trying to 'fix' humanity objectively made things worse, and whatever "plan" he had for otherwise doesn't fucking matter because thats not what HAPPENED. Emperor didn't get a functioning webway, decommissioned space marines, and a civilization of psychic supermen. He got a golden throne to rot on, a galaxy in a neverending state of war, and an Empire that is incapable of winning that war because it is morally opposed to coming up with solutions that are not "the enemy cannot kill millions of us if we kill billions of us FIRST."
