Do the math. A limited resources (IPv6 addresses) distributed over
*another* limited resource (humans running networks) will or will not
run out, depending on the distribution ratio.
As in: if you have 100 cakes and 5 kids, there is no way these kids are
going to eat all the cakes, no matter how liberal your cake distribution
policies are.
We've been distributing IPv6 prefixes for slightly over 20 years now,
and we haven't used up 1% of 1/8 of the IPv6 space yet. The growth
curve isn't exponential, as the number of "ISP like" entities that
will request a prefix from the RIRs is limited - right now, below
20.000 LIRs in the RIPE NCC service region. To give them all a /29
would need half a /14. Now, we have LIRs that are happy with a /32,
and we have others that need (or at least "can argue for") a /19 - but
those are few, like 1-2 per country.
Overall the numbers suggest that all of RIPE land should be fine with
a /10 or /9. Which is 1/512 of the total IPv6 space (or 1/64 of FP001
which is all that is available today).

have you enabled IPv6 on something today...?
