By 2040 you will be able to upload your brain.
or at least thats what Ray Kurzweil thinks.He has spent his life inventing machines that help people, from the blind to dyslexics. Now, he believes were on the brink of a new age – the singularity – when mind-boggling technology will allow us to email each other toast, run as fast as Usain Bolt (for 15 minutes) – and even live forever. Is there sense to his science – or is the man who reasons that one day hell bring his dad back from the grave just a mad professor peddling a nightmare vision of the future?
1 Reconnaissance dust
"These so-called smart dust – tiny devices that are almost invisible but contain sensors, computers and communication capabilities – are already being experimented with. Practical use of these devices is likely within 10 to 15 years"
2 Nano assemblers
"Basically, these are three-dimensional printers that can create a physical object from an information file and inexpensive input materials. So we could email a blouse or a toaster or even the toast. There is already an industry of three-dimensional printers, and the resolution of the devices that can be created is getting finer and finer. The nano assembler would assemble devices from molecules and molecular fragments, and is about 20 years away"
3 Respirocytes
"A respirocyte is a nanobot (a blood cell-sized device) that is designed to replace our biological red blood cells but is 1,000 times more capable. If you replaced a portion of your biological red blood cells with these robotic versions you could do an Olympic sprint for 15 minutes without taking a breath, or sit at the bottom of a swimming pool for four hours. These are about 20 years away"
4 Foglets
"Foglets are a form of nanobots that can reassemble themselves into a wide variety of objects in the real world, essentially bringing the rapid morphing qualities of virtual reality to real reality. Nanobots that can perform useful therapeutic functions in our bodies, essentially keeping us healthy from inside, are only about 20 years away. Foglets are more advanced and are probably 30 to 40 years away"
5 Blue goo
"The concern with full-scale nanotechnology and nanobots is that if they had the capability to replicate in a natural environment (as bacteria and other pathogens do), they could destroy humanity or even all of the biomass. This is called the grey goo concern. When that becomes feasible we will need a nanotechnology immune system. The nanobots that would be protecting us from harmful self-replicating nanobots are called blue goo (blue as in police). This scenario is 20 to 30 years away"
