memoir: email review up to "AI Timelines Scam" (11 July 2019)

I haven't been proactive about getting my writing half-weeks off to a
solid start on recent Thursdays—and I wasn't proactive for most of
today, but in the evening, I got a lot of email review done, and I was
actually in the flow—actually feeling OK about looking at the
history. If I can get into flow about writing the history tomorrow,
then I'll be on track to be alive for the end of the world.
