By your logic, the conversation you're having is pointless. So you do feel like there's a point to life, otherwise you wouldn't be carrying it out. So you're not just ignoring pointlessness, you're participating in whatever the point actually is.
Flaws that can't be fixed...if I managed to fix... Can they be fixed or can't they? And what according to you is the point of fixing them? (There may be one and there may not be one).
Humans are a failed race? What constitutes being a failed race? Not being perfect? What's perfect? Is your version of perfect the same as mine? And if it's not like it matters then why bother killing us off anyway?
