OK, I hope my question doesn’t get misunderstood, I can see how that could happen.
Just a product of overthinking.
Idea is that we can live fairly easily even with some diseases/disorders which could be-life threatening. Many of these are hereditary.
Since modern medicine increases our survival capabilities, the “weaker” individuals can also survive and have offsprings that could potentially inherit these weaknesses, and as this continues it could perhaps leave nearly all people suffering from such conditions further into future.
Does that sound like a realistic scenario? (Assuming we don’t destroy ourselves along with the environment first…)
Yeah I can think of a few, like aging. 10000 years from now kids will be saying, “wow, those poor unevolved savages lived such short lives and only really got to enjoy the first little bit of it before they started falling apart. They even had genetic engineering at the time! Imagine how many people would be alive today if they hadn’t been so scared to edit their genes to prevent aging.” Then their teacher would come over and explain that it wasn’t so easy at the time. There were still so many other problems they had to solve and related genes that need to be modified to avoid undesirable consequences, and let’s get back on topic: how many planets fall under the rule of the galactic empire including our own planet Urth?
