everyone is different. it is believed that everyone is entirely different from what one was 5 years ago. it is a different person in us all the time who keeps evolving in mental and physical world. and we become a grown up person in matter of years. every single cell and tissue including the retina even eardrums get replaced multiple times in one human life cycle.

so technically, you are not the same guy who was born on your birthday. its entirely different person mentally and physically. because our wisdom grows with our experiences so the intellect and level of consciousness is different for the gentleman who was born on your birthday.

to lead a successfully livable life, we receive help from our experiences in the form of memory in association with our intellect as processor of those memory files kept inside a brain like hard disc. which is installed in a computer with a webcam, two stereo microphones and speaker like mouth with an auto adjustable vocal chord. and beautiful potential to gain control over this computer in order to get access to that super console to play live and create results.

like our bio computer (our body) evolves physically and mentally. machines as a computer are evolving. artificial consciousness has evolved to the full potential
