It's really unfortunate that the sound quality is so poor, because I was able to understand some of it and Dr. Arkes is an entertaining speaker and he has important things to share. I only sampled one other video on your channel to see if this wasn't a consistent problem, but even though it was comprehensible, it still seemed to have a loudspeaker-like quality to it. I think that sound quality really might be substantially affecting people's impressions of your videos. Something to keep in mind for the future. Still, great work, Gleb.
