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.
