Of course, different languages come with different trade-offs, but I wholeheartedly agree that Python picked the good side of this particular trade-off.

If proper indentation is so critical to a human parsing of the code that every style guide in the world demands some type of indentation (note the lack of style guides demanding a complete lack of indentation,) then why not use that very same convention to convey that very same information to the compiler?

The C-family of languages is on the unfortunate side of this trade-off: there's one method to convey statement blocks to the compiler (brackets) and another to convey it to the reader (the indentation convention.)

TL;DR: Multiple channels with redundant information run the risk of disagreeing with each other. I don't know if anyone's come up with a catchy phrase for this, or coined some sort of "law", but it's very real. As soon as you have redundancy of information, you automatically inherit the problem of synchronizing the information between channels.
