It's fine to state your own reading of what they said and respond in kind, but dictating that your reading is universal when your comment is directly under evidence that it is not is a big leap.
If you insist on using 3rd party interpretation rather than 1st party intent to decide the meaning of a statement, I've got 16 upvotes on my comments here so others seem to be reading it the same as I.
But we don't need to vote to understand what "until after" means. It's not esoteric philosophical language - my 6 year old would understand it.
"Argument by upvote" is weak, especially in a forum where I can't actually see your comments vote totals.
Also, you are not the first party, so why do you feel so confident in being able to claim sole interpretation of "1st party intent."
They clearly meant that that space colonization was such a far off goal, that the difference in intensely focusing on it and moderately focusing on it won't cause measurable differences in our lifetime.
Or they didn't, I'm not a mind-reader, but I've given just as much evidence to back up that claim as you have yours.
