Nobody said that cretin. What was said is that it appears the minimum
distance between aircraft can be reduced significantly and then GPS
can control the spacing.

And that is completely wrong. Once the spacing has been established GPS
is irrelevant in maintaining it. The minimum spacing can not be reduced
from what it is now unless aircraft can be designed to be unaffected by
wake turbulence. And if that happens GPS will still be irrelevant.
