Dylan F Posted over 2 years ago Is is ethical to try to lengthen the human lifespan? But I believe in the next decade or two, the lifespan gap you mention will narrow greatly. Impact investing will become an increasing popular method for conducting business. There are enormous economic incentives to provide basic necessities (food/water, energy, healthcare, education, etc.) to all peoples because these communities will then be able to contribute back to the global network, just as any community does today. Solar power continues to increase in efficiency and decrease in cost at an increasing rate. This means that it will eventually intersect with fossil fuels in terms of cost and efficiency. Once this trend continues from there, it is hard to imagine not having limitless, virtually free energy throughout the globe. This will greatly enhance the standard of living in remote and poor communities. The medical industry is seeing the rise of a computer science revolution that has enormous promise. In addition to these (and many, many other emerging technologies), the falling cost of technologies will allow poor nations to actually compete in the global market, which would lead eventually to an 'age of abundance'. It has been happening already. Although the gap is large now, the global life expectancy in the 1800s was 37. So even those at the low end of the spectrum are enjoying lives much better than the average person 200 years ago! But it gets better because in this information age we find ourselves in, there is exponential change. We think in linear terms so it’s very hard to imagine what the next few decades will look like. With biotechnology, robotics and (eventually) nanotechnology, some believe we could even be immortal by ~2050. By then we will be much more intelligent than we are now that all ethical dilemmas we predict now will be obsolete. I suppose all we can do is continue to develop technologies, value well-being as the most important thing in life and structure our communities promoting that fact.
