The human brain is self intuitive and is much better than the iPad in learning things and storing memory as well as the speed in which the brain can process information compared with an iPad which is much slower.
The human brain is an intricate network of soft tissue and neurotransmitters that send signals all over your brain that change the way you feel, see and perceive things in reality etc.
The iPad is just a cluster of circuit boards that interact with each other to create the interface on your iPad, so the iPad can retrieve information from its built in memory a lot faster than the human brain.
The human brain is a lot better than the iPad because it can constantly create new neuropathways so you are expanding your knowledge, and the iPad has to be programmed or have an update to change its interface whereas the brain can learn by itself without help also a quick comparison is: the brain stores 3.5 quadrillion bytes and the iPads data storage is 64 billion bytes and the iPad is more energy efficient because it works at 2.5 watts and the human brain works at 40 watts.
