Exactly! In 5 to 10 million years we might notice a change in the eighth
digit for the speed of light. It might be 299 792 457 m/s instead of 299
792 458 m/s. Our descendents will have to go around and change all their
metric (of course) speed limit signs due to the change in the size of a
meter.

Just teasing you, Johnathan, but that's about the level of difficulty
this "changing" of the primary "constants" will cause us.
