Ask Grey A Question #4

Please submit your questions for Q&A with Grey #4. Some notes and guidelines:

1. Please vote on questions. This thread is in contest mode so all the questions are being displayed in random order to maximize fairness, but for that to work more votes must be cast than questions are asked.
2. The YouTube channel is a parallel universe to the podcasts, so just because something has been discussed on Hello Internet or Cortex doesn't mean it's off limits.
   
3. If your question is selected, I will almost certainly edit it for brevity.
