Of particular interest is the ability to implant memories.
‘First of all, someone goes on vacation before you, and pleasant memories such as walking on the seashore and picking up rocks are put on a disc,’ Dr Kaku told MailOnline.
‘Then they're uploaded into your own mind; relax, and there you are at the beach.
‘Feel the wind at your face, hear the sound of the waves, all the sensations – you’ll have a memory of a very nice walk on the beach in some exotic location, that’s what this person before you felt.
‘These things are within the realms of possibility – it’s only a matter of time.’
...
‘We’ll be able to perform primitive forms of telepathy, we’ll eventually record memories, and then Alzheimer's patients will be able to push a button and memories will flood in.
‘Beyond that, the Internet will be replaced by the “Brain-net”, where you can convey emotions and memories rather than just text.’
Further into the future, probably the 22nd century, we could control surrogate robots on alien worlds with our minds, so we can explore space without physically having to go anywhere, according to Dr Kaku.

On telepathy, Dr Kaku says we can already take someone who’s totally paralysed, hook them up to a computer, and allow them to send messages on the internet.
In the future, you could ‘walk into a room, mentally turn on the lights, internet, answer emails, call up for a movie. Indeed the computer mouse will gradually be phased out.
This will be made possible thanks to programmable matter – the dream of creating tiny little dust particles with the power of a PC, known as catoms, that can change their electric charge and be rearranged – all by our minds.
At the moment we are ‘nowhere near getting down to a grain of sand,’ but Dr Kaku insists this can be addressed in the future.
‘In principle, in the future – mid-century – when you walk into a room, you’ll mentally control all computers which are invisible – like Harry Potter.
