Historically people have been able to use whatever tools they want to
*produce* open-source contributions. Nobody has argued that we need some
kind of consensus on whether or not people can write their code in Vim or
Emacs. We do need consensus on tools that are shared by the whole
development community, e.g. CI.

That is to say, "we" are not adopting LLMs. Some contributors are.

This is one of the reasons why I think Simon's proposal is pretty good: it
focusses on the part of the process that exists in the shared space that we
all occupy: the contribution and review process; our growth as a community
of developers who care about the project.

To be blunt, I think this is the best we can do right now. It seems to me
that the *crux* of the most heated disagreements in this thread is about
whether or not use of LLMs is *immoral*. I think it's totally
understandable for people to care about that, in both directions, and I
agree that (if you oppose the use of LLMs) collective action via individual
projects rejecting them can be effective. But it also seems clear that the
GHC developers as a group do *not* have consensus on that question. Maybe
other projects do, especially smaller and less diverse ones. But given the
state of disagreement it seems to me that the only reasonable goal for
a *policy
for GHC* can be to focus on the things we *do *agree on, which I think the
current policy does pretty well.

We should continue to talk about the issues, but I think it would benefit
everyone to stamp out even a limited policy now so we have something!
