"By the end of this century we'll have the technology to make carbon capture"

We have this technology already. It's called "trees". Whether we choose to use it is a different matter.

Environmental sustainability - like most hard problems in the world today - is not so much a technological challenge as a political one. I do believe technological progress in the future is a certainty, and will bring many good things with it, but it will not do the hard work of encouraging humans to do the right thing. That is something we have to do for ourselves.

That's the bad news. The good news is that this work is something we can do immediately, right now, without waiting for the hope of our utopian Star Trek future to become reality.
