Here, I think you are wrong. I strongly suspect that while the high-level features of programming languages are chosen for human consumption, the implementation details and tooling are often chosen arbitrarily, or for machine-convenience. For example, I don't generally consider language environments where the leading white space on a line matters, or languages where trailing white space matters to be "designed for humans." Computers might be good at counting spaces, but we're mediocre at visually estimating the width of a blank area in text. Such an environment asks the user to develop more machine-like skills rather than attempting to accommodate their weaknesses.

Or it asks the user to use tabs? Or an editor that inserts spaces when you press tab? Indentation has never been a stumbling block for anyone but the most junior of programmers.

Sure, there are all sorts of ways to lessen the pain of syntactically significant indentation. Indeed, I'd say that the annoyance can be made sufficiently small that by the time someone is an experienced enough coder to recognize that the pain has always been communally self-inflicted, they're too used to it to care.

Do also note that I'm not saying that indentation is by itself bad.
