> ... you should worry that your car is going fast.

Only if we know of an intervention that will likely slow the car down and the risks+cost of that intervention justify the benefit.

Otherwise, we worry without purpose.

EDIT: I will say that there is a philosophical question here related to "basic research" / "pure science" / "fundamental science." Usually just "knowing new things" eventually proves valuable, especially in a long timeline. So in that sense, TFA could be important.
