Thats right, but you started your sentence with "All I know is..." and
listed two truths, but in fact these are not all you know. I kinda tricked

you, since I started with having you randomly pick two primes {non-2
both}, multiply them to generate C. So you know that C is odd, as are
C+2 and C+4, etc, so the probability of prime approximation needs

Before I belabor this whole thing more than I already have on a list
that is not primarily about primes, let me just do this: I wish to put
together a paper on this topic which I have been thinking about way
too much for the past year, regarding predicting the next record prime,
then posting it on a website.

I wish to draw parallels between that concept and predicting the time of
the singularity, for oddly enough, both problems, predicting the
singularity
and predicting the next record prime, present similar paradoxes.

Unfortunately I dont expect I will have it ready by E5, because I
