Haskell also comes to mind. Errors are so well handled in that language, you probably won't notice that they are so well handled. Because of the way things are structured, errors are rare (so no need to check them). When they are present, there are a number of techniques from "Maybe" types to "Error" monads to throwing "IO" monad errors. The "Maybe" type is particularly interesting as it ensures that the user will check the error, and provides convenient notations and combinators for doing that checking.

Third, the keys are editable ... Thus, you're really in control of your computer.

Not if you are on an ARM instead of Intel. Microsoft's behavior makes it pretty clear they would like to do the same on Intel even if they can't right now.

[Your mom] doesn't know or care about signing keys and hashes.

Which means that it prevents your mom from running alternative operating systems unless that system (1) pays $99 to Microsoft or (2) requires her to fiddle with keys and hashes.

if someone attempts to transfer the same bitcoin to two different people, the person who gets it is the person who had more computational effort go into recording them as having it

Wait, what? How much computational effort does it take to spend a bitcoin? Would I have to worry about accepting bitcoins with weak transaction histories? Who's responsibility (buyer or seller) is it to ensure the transaction is recorded with enough effort? This sounds like a scary and dangerous way to do things. How is this not a problem? (Just to be clear, I'm asking from honest ignorance.)

Unrelated question:

If people stopped mining (perhaps because the reward got low enough), Bitcoin would collapse.

Could you expound on why it would collapse?

Bitcoin will let us see if money is something that can truly exist without government

That experiment was tried years ago in the form of coins minted from precious metals. Yes, it does work. It does, however, bring certain disadvantages (e.g. uncontrolled fluctuations in the monetary supply, people trying to corner the market, etc.).

I can't find the quote at the moment, but I think Feynman once said that the problem was like trying to use a flash light to track and hit a running person that is holding a small mirror ... from a football field away ... in the dark (i.e., only way to track them is by the reflection when you hit).

(Disclaimer: IIRC, the original quote was in reference to the Star Wars program where the distances involved made things like radar less precise/effective and the use of lazers required a prolonged "hit".)
