+
+## Abstract
+
+It is currently difficult to see the status of Carbon explorer and where effort
+is needed. We propose creating a AreWeYet-styled dashboard to address this.
+
+## Problem
+
+While the Carbon project has many published documents, it can be a challenge to
+get a high-level picture of work that has been done and work that remains to be
+done. This can make it difficult to both track its progress and identify
+contribution areas that will have the biggest impact. Left unchecked, this can
+lead to the team equivalent of micro-optimization where resources are deployed
+in a way that isn’t consistent with high-level goals.
+
+## Background
+
+### AreWeYet
+
+Mozilla, a non-profit behind many Open Source projects, has created and utilized
+what is known as the AreWeYet meme as an approach to solve the aforementioned
+problem. In this approach, a highly structured dashboard is built that
+succinctly states a goal, what its status is, and links to issues or other means
+to track subgoals.
+
+One example is [“Are We XBL Still?”](https://bgrins.github.io/xbl-analysis/))
+which tracks a project to remove all XBL bindings from Firefox. The general
+format is a question, “Are we X still?”, followed by a list of items that, when
+complete, means the answer to the question becomes yes. Other examples can be
+found on Mozilla’s [Areweyet page](https://wiki.mozilla.org/Areweyet).
+
+The success of this methodology has led to other projects, such as Rust,
+adopting it.
+
+### Carbon Explorer Status Brainstorm
+
+A portion of the June 29th, 2022 Carbon weekly sync was used as a brainstorming
+session to identify both work that has been accomplished and work that remains
+for the Carbon explorer tool. While a comprehensive snapshot in time, there
+wasn’t an explicit agreement on how to utilize this document or keep it updated
+going forward. This proposal is the logical next step in this work.
+
+## Proposal
+
+We propose creating and utilizing an AreWeYet for the explorer project. The
+methodology has already been successful elsewhere and we already have the data
+collected for the explorer project. Although this proposal narrowly targets
+Carbon explorer, experience with this methodology may indicate value for its use
+elsewhere.
+
+## Details
+
+In summary, we propose the creation of a new page on the carbon-lang Wiki called
+“Are We Explorer Yet?”, population of this page with results of the explorer
+status brainstorm, and the creation of issues for parts that are not complete.
+
+The following section will be used as the basis for the “Are We Explorer Yet?”
+page. Items that are specifically out of scope for this AreWeYet are C++ interop
+(likely never a target for explorer), metaprogramming, parallel programming, and
+coroutines. The last three are likely substantial enough to merit their own
+AreWeYet pages.

+## Alternatives considered
+
+The default alternative is status quo where carbon explorer progress isn’t being
+tracked from a high-level. Due to the problems outlined in the problems section,
+this seems like an undesirable option.
+
+Another alternative is to use github issue tags and come up with a custom search
+to see the outstanding issues. This has the benefit of being fully automated. On
+the other hand, it would be difficult to get a hierarchical view which is useful
+to being able to grasp the big picture.
