The commenter claims Musk hasn't achieved anything at all, other than give some tech demos.

I'm perfectly entitled to ask what they've achieved themselves that puts them in a position to so casually demean what, by most people's standards, are quite considerable feats.

What OP has or has not achieved is irrelevant in my opinion. I think it's better form to just refute the criticism and leave OP out of it. But it's up to you of course.

In the meanwhile you've taken the entire conversation off course to serve as the politeness police.

I'm not sure that OP's accomplishments are relevant in this case. You don't have to be above someone to point out mistakes. That is not to say I agree with OP, only that I disagree with your statement.
