Smart people know that you can't predict or plan for anything on anywhere close to that time horizon. The only plan is be adaptable.
You can build contingencies and hedge bets. You can plan. You just can't predict what will happen so it's playing the odds.
Yep, the only thing that's sure is that children of said smart people will suffer their whole life so these smart people could give a bit more money to the fossil barons.

And that's exactly what the question was.
You seem to consider yourself in the "smart people" ranks, so what's your big plan for adaptability?
