It is distasteful to make such accusations. Specially when the author has specifically left out the calculation and merely suggests of a “fraction” which is to be discovered with time.
It's not the only aggrandizing element of the blurb. The whole thing is baseless prediction presented as though it's hard truth, which is either deliberately dishonest or unconcerned with whether it's honest. If it's tasteless to point that out, I'll happily be crass about it.
