Be careful where you go with that, you're right what you say about some medical interventions weakening future generations genes. For example i can't see my hand in front of my face without my specs and had we had kids I dare say at least one of them would have been short sighted too. In our hunter gatherer days I dare say I would have starved to death so my genes wouldn't have affected the next generation. Humanity's main weakness is compassion and where would we be without that, although it does seem somewhat lacking nowadays, we as a race don't like to see others suffering. Eugenics in principle works to some extent but who would want to see it put into practice? There are also many examples in the animal kingdom of living past their productive life, many primates do and so do elephants.
I agree it's not simple.
Just pointing out the potential problems. I suppose all the previous civilizations thought they were the pinnacle of human progress, and the way human society should go. Yet, only when those civilizations are dead, we get to discuss what got to them, through history.
For our civilization: it's clear we are destroying the planet, and to me it seems people are getting a bit dumber - shorter attention spans, especially for the younger generations. Doesn't look too promising.
Not claiming I have any idea how to correct that - there are too many things to consider (practical, ethical, economical...).
Recreational drugs are a big factor in the way people behave these days, it's a massive market and the supply is most definitely there for the demand.
And due to the recent snowflake generation getting their way there is a vastly different attitude towards discipline with younger people nowadays which has basically given them free reign to run riot, and why we have so much trouble on our streets.
When i was a kid we all had penknives for example, but i don't recall anyone ever using one as a weapon. There was a kid stabbed to death near me 2 days ago, with a CCTV video showing exactly what happened, and the attackers can only be described as savages.
But when people are caught doing wrong you then get the snowflake defence liars doing their best to make them look good in court and they get their result far too often, meaning the criminal tends to get preferential treatment over the victims.
The horrible reality about all of this is that there isn't really a fix either. Drugs are already illegal, and if you look at places like USA where the threat of really long jail time, unlike our paltry sentencing, still doesn't seem to affect the crime statistics then it all seems rather scary when you think how bad the future is going to be.
