Oh you're absolutely correct about that. Jobs in particular needs to be scrutinized.
But if that was the point of the article a few paragraphs under the section "History of switching power supplies to 1977" already accomplished that.
The article reads like it was written by a power supply enthusiast (who knew?), and the author did a good job of drawing me into the history, technology. It would have still been an interesting read without the "bookends".
A couple of good examples of (much) earlier switching supplies from Ken's site:
1) 1960s-era tech used in the Apollo Guidance Computer: https://www.righto.com/2019/08/reliable-after-50-years-apoll...
2) Mercury thyratons used in 1930s-era Teletype hardware: https://www.righto.com/2018/09/glowing-mercury-thyratrons-in...
Might be some other candidates as well, but those are a couple of the more interesting ones he's gone over.
Journalism doesn't become any less interesting by making connections to the greater outside world, especially when it's timely/contextually relevant.
