The bits don't add up

In this text, I don’t want to add anything new to quantum mechanics.I just want to help people understand it, to make learning a little easier.For example, a child, a teenager, or anyone curious about the subject — they want to know and understand.But right now, quantum mechanics is presented in such a way that after reading, a person still can’t find a simple answer to the question: “what actually is this?”That’s why I want to make it easier for everyone who wants to understand.

At first glance, the ultimate limit of computation seems to be an engineering issue. How much energy can you put in a chip without melting it? How fast can you flip a bit in your silicon memory? How big can you make your computer and still fit it in a room? These questions don't seem terribly profound.
