thanks for your long reply.

8 billion is really high. i didnt knew that.
i know about sickle cell anemia and such stuff. but i think its still better to delete a disease causing gene even if it might give advantage in another case. i guess any of such genes might be replaced by evolution or genetic engineering one day easily. if humanity wants to save these genes then just implement them into plants, animals whatever in the labority so humanity can use them if its necessary.

"modern technology can help you deal with all diseases (even acne and bad sight)". no. i use antibiotics and used 3 year accutane. there might come some virus on the market so maybe a new symptom killing medicine. but however no medicine and technology has really cured.

besides that you are right with everything you say and of course most would prefer the old fashion baby making yes. still it doesnt give much answers to my questions.
