Sorry for being notoriously informal, it means that certain
developments start to lag relatively to the hitherto linear log plot
of some relevant metric vs. time.

Hmm, let's see. (Btw, would you let me have a copy of your algorithm
of assigning these numbers to actual events forecast? Big thanks).

Anything from zero (we can't go negative, can we?) to some
absurdly (really really transastronomically postabsurdly) high number.
(If 'number' and 'human' and 'individual' still mean
something by then, that is, things like timelike closed curves and
timespace engineering considered. Recent news about GUT unification
energy reconsideration considered, nothing will ever surprise me).
> 2) Median physical mass of each descendant in 2098
If physical mass has a meaning after some timespace engineering (show
me a proof you can't do that by 2098). Even if you can't build these,
I still have no idea how many persons can really fit into the volume
of a glass of water, whether quantum computers, or no. What's the mass
of matter in the PS lightcone @ 2098?) (And molecular circuitry we
will certainly to be able to do by then. Urgh. Was this a forecast?
Forget whatever I said).
> 3) Median age till death of each descendant in 2098
Age? (Well, if you go Lamarckian, identity stops having its canonical
meaning). Death? What's that?
> 4) Median number of immediate descendants of each descendant
If identity still exists, as does timespace.
> 5) Median distance each descendant lives from where he lives
Urrr. 'Distance'? 'Live'?
> 6) Modal religious affiliation of descendants
'Religion'?
{Allright, I've been deliberately nonconstructively dadaist (within
my current mental model), but point (still) is: you can't be sure what
actually happens. Personally, I would adhere to more conservative
scenarious (you'd be surprised), but no one can't be certain. No,
sir. Not even Robin Hanson.}

The distinction is not practical. Yes you would, much good this will
do you.
