💌 A valuable message from Russ Cox

Over on the golang-dev mailing list, Russ Cox posted a valuable message:

Go development is not isolated from world events; work on Go always comes second to more basic concerns like personal and family health and safety. Nearly all of us are working at reduced capacity these days. I expect that capacity to drop further over the next few months.


If our own working capacity is reduced but we keep the same timelines, then we must reduce the scope of what we expect to be in the release. Some new features or planned won't make it. That's OK - we'll get them next time. We all need to accept that, for our own work and work by others.

Most of all, let's all please be extra kind and charitable with each other. It's always good advice to remember that you don't know what external stresses are affecting the person on the other end of the email, review thread, or GitHub comment, but it's especially important now.

The above is just a quick summary of the main points, but it's also worth reading in full. Thanks Russ.
