I personally don't see a problem. Writing shouldn't be limited to experts, as long as person clearly identifies what it is and what it isn't. Both in the title and introduction of article it clearly says that it is experience of person who is new to field. Which to me implies that whatever they are saying should be taken with grain of salt and that they might not have exhaustive or fully accurate knowledge. It doesn't claim to be "ultimate reference book for everything hardware". That doesn't change the fact that that's experience they got as beginner. It's up to you decide whether reading beginners experience is useful to you.
On the other hand it also means that the problems person encountered are likely nothing extraordinary. And that it's something other beginners should watch out and further research, as they are likely to encounter similar challenges. Beginner articles can also be useful for those who have no idea where to start as means to gather keywords for further reading.
Having beginners share their experience might not be useful for most experts. But it can be helpful to highlight common pain points and areas of potential improvements for educators and people making tools.
Yeah, I think it's fine, and even very positive, to be sharing their view. However, I do agree with the sentiment that "hardware" used as a generalization is confusing. There are lots of different kinds of hardware and the article does not clarify it anywhere, although you can derive what they mean through the later descriptions. I had to re-read the intro once I had figured out what "hardware" meant.
Personally, I'm also a software engineer who ventured into hardware, and even am now professionally doing hardware design. I find that perspective worthwhile. But I am an ASIC engineer, which is a very different kind of hardware than PCB design or integrating ICs on a breadboard. The lessons and realities of each are different. So I would find it helpful if the post (and title) clarified what specific field was being discussed.
