I enjoyed his entire series on youtube, but I personally think it's nuts to make it on a breadboard. Whenever I've built systems of this sort I've always opted for point to point soldering.

In the videos he talks about the importance of using high quality breadboards, but even so, it's so easy to knock a wire out accidentally that leads to having to trace every connection to figure out what went wrong.

But from a pedagogical standpoint and having people follow along with a minimum set of skills, I get it.
