¹¹I shall just briefly mention another crucial difference between brains and ordinary computers: An ordinary computer has hardware and software, and these two are separate. The same hardware can run different kinds of software, and the same software can be used on different hardwares. In fact, you can take software from one computer and download it to another, similar computer and it will work on that new computer as well. However, in the brain, it is difficult to see any clear distinction between the software and the hardware: nobody ever downloaded software into their brain. Such a division between hardware and software is part of what is called the von Neumann architecture, named after the great mathematician John von Neumann.
