Sorry are there actually developers who don't use VCSs in 2017?

Yup. And it horrifies me every time.

This is a nice circus trick. I wonder if it helps productivity, compared to a VCS.

And help it definitely can. For some people, pictures and motions are easier to remember and reason about, even in such a text-heavy area as writing code.

If he's verbalizing his thought process it might actually be better than the average comments you get on code. Might actually have to play around with dictating what I'm thinking at key points in the process.

Push-to-talk helps a LOT. When I first started streaming I would just have a running stream of consciousness filled with lots of "uhhhhhh" and swears. Using push to talk helped me become more conscious of when I wanted to speak and since then I've gotten better at self editing and don't have to use push to talk as much.

I sounds like a useful super-blame, but I would still use a VCS. It's so easy!

I wonder if the VOD URIs are consistent enough that you could automate adding a link to the VOD+timestamp to your git commit descriptions...
