I dont know how many research or keep up with emerging technologies on this forums. I also do not know how many are aware that we are at the verge of a Biotechnology revoloution and what this could mean.
We do have the ability to Extend life of simple tissues, cells etc... But we also have the ability to block genes in Mice to enable them to have a Life Span of around the equiv to 200 Human Years. Scientists think within the next 5-10 years Aging in Mice.
So slowing down Aging in less Complicated animals is poosible and not science fiction. Ultimatly I believe and so many scientists in fields such as biotech and nanotech believe that slowing down or stopping aging is inevitble in humans.
Now to make some things clear. Im being totally serious on this topic, its not such a far fetched idea anymore. We have the enabling technologies and they are moving forward quite well.
Im not saying that you will live on longer and you're family dies around you, that will not be the case, Since they will have access to these enhancments just as much as you, Of course at first they will be for the more wealthy and new technologies always are. But eventually they will come down in price as demand grows.
Not only might we be able to make us live longer, we may be able to geneticly engineer ourselfs in many ways. whether it be intelligence, muscle strength, better eyes, better hearing... Possibilities could be endless...
But while we are in this technology revoloution, Nanotech will be picking up and maturing, Enabling us to have far more capabilities.
the possibility of Nano-red blook cells. Using 10% of these mixed with normal red blood cells will enable you to hold you're breath for upto 4-5 hours. You could run a few hundred meters without breathing.
Also more far off in the future, millions of nanobots that go around the blood stream and fight off diseases, viruses and fix genetic faults. This is still the most extreme capability. But ermeging technologies are showing that it may indeed be possible.
Whether most like it or not. By the end of the 21st century we will have changed drasticly. Far more than any of century. Post-humans could be common, possibly an even more divide between wealthy and poor countries. But by then other technologies could help thos countries far more than today.
We KNOW its possible to engineer ourselves. Yes it is not a full understood yet. but we are rapidly advances. Every 10 years there is a paradigm shift, Technology advancements Double every 10 years. So all the advances took 10 years will take 5 years then 2.5 years ...
the model ray kurzweil has put forward, at todays rate of progress we will see 100 years of technological progress in within 25 years. and at todays rate of progress we will see 25.000 years worth of technological advancement in the 21st century.
these are TRUE trends of technology and this is what they show. SO they are not up in the air predictions, they are predictions with plenty of research behind them
http://news.bbc.co.uk/1/hi/uk/4003063.stmCheck out that article on human life span may reach 1000 years and beyond. And the first human to reach 1000 could be 60 already.
Other models have showed that the human life span s increasing 3 months every year. By 2010 these are expected to reach. 1.5 years every year. So basicly the human life span may increase faster than you can age.
you think you are going to retire around the age of 60?
welll most of you. But Im confident and so are many far more educated people that human life span will increase through the technologies we are advancing in today.
If 1 were to get an enhancment, showed it off... Their friends like it, They get it done and trend will continue. Especially if it becomes cheaper
Who are we to take God's work into our own MANMADE hands? Even if the scientists are absolutely correct in their evolution theory (it is a GOOD theory, but its still just another theory) that doesnt disprove God or nature being God's nature. If we change "humanity" how is that Gods work, God's nature?
What about the people who wont be able to afford all of the transhumanist upgrades, or the traditionals/religious who would refuse them? Do they deserve to get squashed in the "evolutionry chain" for remaining obsolete humans as compared to "superhuman" trans/post-humanists with far superior mental/physical abilities? All HUMAN dignity will be lost to the trans and post-humans, how couldnt it be? Why arent yu good enuogh to live the life as the person you were meant to be, for as long as you were meant to be?
They struggled with this for several years before finally passing on.
