Things have a tendency of working out in the end. It's not guaranteed to happen, but I don't feel like we're anywhere near the point of losing hope being reasonable.

Many of those points also seem unnecessarily pessimistic to me, but I don't particularly want to discuss them in further detail because others will probably do it instead, so I'll refrain from elaborating
