We are talking about Mars colonization prediction. Read first before comment?

This is the OP:

Another reminder that Elon Musk routinely lies about timelines. If Mars colonization had followed the timeline laid out here, we'd be three years from having lots of people on Mars.

And none of the ones you mentioned are talking about Mars colonization. I was just highlighting that holding people just pontificating about possible futures should not be held to the same level of scrutiny as a person saying "my company will do X in y years/months, give me money in advance".
