No longer need strokes and neurodegenerative 
diseases rob people of speech because we can turn their brainwaves directly into 
words.
But this is only the beginning. 
Neuroscientists are going to make the mind meld look like child’s play. Mankind 
is merging with its machines.
The process began centuries ago with simple 
devices such as eyeglasses and ear trumpets that could dramatically improve 
human lives. 
Then came better machines, such as hearing 
aids; and then machines that could save lives, including pacemakers and dialysis 
machines.
By the second decade of the 21st Century, we 
have become used to organs grown in laboratories, genetic surgery and designer 
babies.
In 2002, medical researchers used enzymes and 
DNA to build the first molecular computers, and in 2004 improved versions were 
being injected into people’s veins to fight cancer. 
By 2020 we may be able to put even cleverer 
nanocomputers into our brains to speed up  synaptic links, give ourselves 
perfect memory and perhaps cure dementia.
But inserting technology into human brains is 
not the only thing going on. Some scientists also want to insert human brains 
into technology.
Since the Sixties, computer chips have been 
doubling their speed and halving their cost every 18 months or so. 
If the trend continues, the inventor and 
predictor Ray Kurzweil has pointed out that by 2029 we will have computers 
powerful enough to run programs  reproducing the 10,000 trillion electrical 
signals that flash around your skull every second. 
They will also have enough memory to store the 
ten trillion recollections that make you  who you are.
And they will also be powerful enough to scan, 
neuron by neuron, every contour and wrinkle of your brain.
What this means is that if the trends of the 
past 50 years continue, in 17 years’ time we will be able to upload an 
electronic replica of your mind on to a machine. 
There will be two  of you – one a 
flesh-and-blood animal, the other inside a computer’s circuits.
And if the trends hold fast beyond that, 
Kurzweil adds, by 2045 we will have a computer that is powerful enough to host 
every one of the eight billion minds on Earth.
