This is the age of social media. This person has hit the front page of HN twice now. That's a commercially valuable skill.
At this point, having proved that can do something commercially valuable a couple times now, I think they should run with it. Start a YouTube channel. Keep racking up views. Then, eventually, do partnerships and sponsorships, in addition to collecting AdSense money.
If you like to write or perform for other people, you can monetize that now. This person is good at it. They should continue.
