1 . Ray Kurzweil is an inventor and futurist with some interesting ideas on how humans will soon be able to live much longer than the average 78 years they do now. If Kurzweil is right, this is a question we’ll have to ask ourselves in the near future.
The first challenge is how to stop our bodies from getting old and dying. Kurzweil doesn’t see this as a problem. With gene technology we’ll soon be able to “turn off” genes that cause ageing and disease. This technology is getting cheaper and advancing at an incredible rate. Kurzweil believes that from every year after 2023, we’ll be adding more than a year to the average life expectancy. He also expects that within the next 20 years, we will have ‘nanobots’ in our blood. These tiny robots will automatically keep our bodies healthy and free from diseases by finding damaged cells and destroying them.
Of course, if we’re all going to live longer, then there are going to be more of us on this already overcrowded Earth. Many people think there are likely to be problems with resources such as food and energy. Kurzweil doesn’t agree. He says that the same technologies used to increase our life expectancy will also be used to help with food production and energy needs. For example, he says, sunlight can potentially give us 10,000 times more energy than we currently use. We just need to develop the technology to capture it and make it cheaper. There are also new technologies that can recycle water extremely cheaply. This means that dirty water can be made clean again at a very low cost. When you consider that 80% of disease in the developing world is because of dirty water, you can see how this technology might help change the world.
But what are we going to do with all this extra time? Won’t we all get bored? Again Kurzweil says ‘no’. For a start, we won’t be stuck in old bodies. We’ll stay young for years. This will mean we’ll be able to experiment with many more things than we can now. We’ll also see huge developments in virtual reality technology that will keep us entertained for years.
The future according to Ray Kurzweil looks good — and we might just be around to see it.
