What's happening right now could still be a very unlikely anomaly and everything may change back to "normal" soon. Or it isn't. Hard to judge for me, I'm not an expert.
And if it isn't I'm sure they'll just magically figure out economically viable fusion or spray some aerosols into the atmosphere or somehow just magically fix everything.
I'm sure everything will be fine. That's why I'm not having kids.
