Basically, this advice either boils down to "get out if/while you can", or else we're going to have to take some amazing steps to even get a small portion of the population out of the gravity well.
Which is actually good advice from one perspective - it's a very good negotiating approach.
We know that all paths we see before us seem to lead to epic population tragedies.
The cost of each of them is almost unlimited, in terms of taking away a meaningful future for humanity.
The private sector very strongly resists any attempt to do basic non-commercial research that can lead to a solution to any of these tragedies (and in fact is at least the indirect cause of many of them).
The reasonable answer, without requesting it, would seem to be an increase in funding by many of the nations of the earth for basic research. An increase in space exploration by China, for instance, would lead to a new space race, meaning more research and education.
More research and education will lead to progress towards solving basic problems, and possible escape from earth.
But for now in the US, conservatives think it will lead to more liberals, so it will be opposed strongly until they fear China enough to allow some progress.
