I found the quote amusing specifically because of this ambiguity (modulus your first point - the question of values seems tangential to me).

I found the mix of optimism (ie. the assumptions that no extinction type events will occur, and that there will be a continuous descendant type relationship between generations far into our future, etc...) and pessimism (ie, the assumption that, on a large enough time scale, most architectural components traceable to now-humans will become obsolete) poignant.
