This is a huge debate in the science universe.This is also a thing you are Able to do in the game cyber punk 2077.
The mind is a huge part of the body.It is also quite sensitive, if you hit it too hard then you can damage it severely and sometimes prementimantly. Now uploading the mind is based on 3 assumptions one of which is
- Physicalism-This means that everything that we can learn about the mind can be found inside the brain itself.
- Scalability-This is that when we understand the mind and all of its parts can make a digital mind copy.
- Computability-This is when the consciousness can easily and accurately be simulated using computers and coding.
Though all these assumptions have been debated for a long time.Many people have their own opinions on the topics and so this has over the years became a little controversial.
Now lets talk more about the brain.So the brain is actually a really co p,ex thing all humans have.It has 100 billion neurons communicating through 1 million billion connections. These neurons are sending signals through your brain at 1000 signals/second,but now if you multiply that by all the neurons your brain produces 1 quadrillion signals/second. There are also many other things in the brain doing various tasks.
The Neo cortex holds is the outer layer of the brain and holds things like:
Though the consciousness remains unallocated.Precueus has the biggest part of the human consciousness but there are also many little small parts of the brain that play a role in this.
We know that hormones like serotonin(effects how we feel or mood) and histamine(our ability to learn).Our current machines are not as good and advanced to perform tasks like brain mapping.Though great methods like cutting the brain into little peaces can be a great method so then we can make a accurate map of the cells by using a electron microscope.
Though scanning the brain and accurately mapping is it hard work.We might even have to look at every single part that makes up the whole brain. But to map out the whole brain and upload it can use as much as more than all the data on earth.
Though if something happens to the machine that has uploaded your brain and has all your consciousness then you might be stuck in the machine with paranoia and endless pain.
You could though cone your self and have a digital version of your self co-exist with you. With you being digital after a mind upload you can do things like go to Jupiter and answer the questions no one has a answer to, whats under Jupiters atmosphere.You could also skip parts by making time go faster for you.The longer your digital version lives the more they learn.You could do anything like change your personality and you could also remove memory that bugs you.Though there is a down side.The longer the digital version of you lives the less sympathy you will start to feel for the actual humans.
This may not be possible as the brain is too complex to clone.So you may not experience immortality, which is some situations is a good thing. For example if a leader starts attacking other country’s in war like hitler, the they will rule for a REALLY REALLY long time.But if you really do want to feel immortality the only thing you can do is play cyberpunk 2077.
