I think it's important to avoid "Rapture thinking". For those unfamiliar, a certain subset of Christians believe the cataclysmic end of the world is imminent, but that they will be whisked away to heaven beforehand. Therefore they discount the future.

While I think technical advancement of the type we hope for is obviously far more likely than such a fantastical event, we should proceed as though it is an inevitability. We must accept that the climate cake we've mixed is baking, and we should plan for a worst case outcome wherein the effects of climate change are significant and no or not enough great technologies emerge to mitigate them. I believe there will be a way forward even so, but we will face significant challenges.
