I was referring to winter next year. 0.12 isn't scheduled until the end of
the year, according to Wladimir. I explained where this figure comes from
in this article:
https://medium.com/@octskyward/bitcoin-s-seasonal-affective-disorder-35733bab760d
It's a fairly simple estimate based on previous growth patterns.

OK, it could be. But do you think this debate will play out significantly
differently if you are right, I am wrong, and we have this discussion next
summer instead? Because in several years of watching these debates, I
haven't seen much change in them.

Are you sure about that?
What if Gavin popped up right now and said he disagreed with every current
proposal, he disagreed with side chains too, and there would be no
consensus on any of them until the block size limit was raised.
Would you say, oh, OK, guess that's it then. There's no consensus so might
as well scrap all those proposals, as they'll never happen anyway. Bye bye
side chains whitepaper.

No. What I meant is that someone (theoretically Wladimir) needs to make a
clear decision. If that decision is "Bitcoin Core will wait and watch the
fireworks when blocks get full", that would be showing leadership .....
albeit I believe in the wrong direction. It would, however, let people know
what's what and let them start to make longer term plans.
This dillydallying around is an issue - people just make vague points that
can't really be disagreed with (more nodes would be nice, smaller pools
would also be nice etc), and nothing gets done.

I never said Bitcoin is broken in the long term. Far from it - I laid out
my ideas for what will happen when the block subsidy dwindles years ago.
But yes, it's hard for me to care overly much about what happens 30 years
from now, for the same reason you probably care more about what happens
tomorrow than what happens after you are dead. The further into the future
you try and plan, the less likely your plans are to survive unscathed.

I think I see one of the causes of disagreement now.
I will write more on the topic of what will happen if we hit the block size
limit soon, maybe this evening. I have some other tasks to do first.
Regardless, I don't believe we will get any useful data out of such an
event. I've seen distributed systems run out of capacity before. What will
happen instead is technological failure followed by rapid user abandonment
that pushes traffic back below the pressure threshold .... and those users
will most likely not come back any time soon.

I disagree that'd be the outcome, but good, this is progress. Now we need
to hear something like that from Wladimir, or whoever has the final say
around here.
With respect to the fee market: I think it's fairer to say Gavin wants a
market to exist, and he also wants supply to be plentiful. 20mb limit
doesn't actually mean every block will be 20mb the day after, no more than
they're all 1mb today. Miners may discover that if they go beyond 5mb they
have too many orphans and then propagation speed will have to be optimised
to break through the next bottleneck. Scaling is always about finding the
next bottleneck and removing it, ideally, before you hit it.
