📝 Original message:Thanks for your response Ariel. It would be useful if you responded to
specific points I have made in the mailing list post or at least quote
these ephemeral "people" you speak of. I don't know if you're responding to
conversation on the IRC channel or on social media etc.

> The argument comes from a naive assumption that users MUST upgrade to the
choice that is submitted into code. But in fact this isn't true and some
voices in this discussion need to be more humble about what users must or
must not run.

I personally have never made this assumption. Of course users aren't forced
to run any particular software version, quite the opposite. Defaults set in
software versions matter though as many users won't change them.

> Does no one realize that it is a very possible outcome that if LOT=true
is released there may be only a handful of people that begin running it
while everyone else delays their upgrade (with the very good reason of not
getting involved in politics) and a year later those handful of people just
become stuck at the moment of MUST_SIGNAL, unable to mine new blocks?

It is a possible outcome but the likely outcome is that miners activate
Taproot before LOT is even relevant. I think it is prudent to prepare for
the unlikely but possible outcome that miners fail to activate and hence
have this discussion now rather than be unprepared for that eventuality. If
LOT is set to false in a software release there is the possibility (T2 in
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-February/018380.html)
of individuals or a proportion of the community changing LOT to true. In
that sense setting LOT=false in a software release appears to be no more
safe than LOT=true.

> The result: a wasted year of waiting and a minority of people who didn't
want to be lenient with miners by default.

There is the (unlikely but possible) possibility of a wasted year if LOT is
set to false and miners fail to activate. I'm not convinced by this
perception that LOT=true is antagonistic to miners. I actually think it
offers them clarity on what will happen over a year time period and removes
the need for coordinated or uncoordinated community UASF efforts on top of
LOT=false.

> An activation mechanism is a consensus change like any other change, can
be contentious like any other change, and we must resolve it like any other
change. Otherwise we risk arriving at the darkest timeline.

I don't know what you are recommending here to avoid "this darkest
timeline". Open discussions have occurred and are continuing and in my
mailing list post that you responded to **I recommended we propose
LOT=false be set in protocol implementations such as Bitcoin Core**. I do
think this apocalyptic language isn't particularly helpful. In an open
consensus system discussion is healthy, we should prepare for bad or worst
case scenarios in advance and doing so is not antagonistic or destructive.
Mining pools have pledged support for Taproot but we don't build secure
systems based on pledges of support, we build them to minimize trust in any
human actors. We can be grateful that people like Alejandro have worked
hard on taprootactivation.com (and this effort has informed the discussion)
without taking pledges of support as cast iron guarantees.

TL;DR It sounds like you agree with my recommendation to set LOT=false in
protocol implementations in my email :)
