If I could show you where to find a better place to learn, would you still consider me to "mind my own business"
I am not a knight crusader appointed by HN. But I would be happy if people got a better appreciation of things others love. And that needs some constructive critique at times. And at HN I try to do that whenever I can.

Someone even mentioned Ben Eater's videos on SC & PN Diodes & P-N-P/N-P-N transistors. I liked those too when I was learning. Finally the first 10-15 pages in Chapter 1 of Milman & Halkias (PDFs widely circulating) are such a clear read, if something still doesn't click.
For the deep dive details I mentioned in parent post, follow 6.004 Computation Structures' first few lectures. Nand2Tetris lectures also cover how circuits are built from these basic units to make functional units of computer (Bonus: they used to have a simulation software with the book which was neat).
This will build a conceptual model of whats going on in these tiny semiconductor bits - unlike other places which throw in a bunch of facts & expect you to build on top of them
I think the article is an excellent introduction to the subject. Maybe the videos explain things better, but I didn't watch them, sorry. I'd much prefer to read a 5m article than 2hrs of video, and I think that's pretty common here. I personally think this fits great on HN.
Edit: Second video was very nice; it's short and sweet and covers the same material as the article. I still prefer the article, but some may prefer the different format.
I started with a disclaimer: If you know nothing - absolute zero. If this was the first time you heard about it. And it does the thing its intended to do i.e. tell a concise history and introducing some of the jargons
To each his own. I think the OP article is pretty poorly written & handwavy. My complaint of not showing charge flow or polarities still holds.
In other words, the DigiKey page fails to answer the question: How do transistors work, anyway?
No, it is to first familiarize What is a transistor anyway?.
If I had to teach Complex Analysis, I would start with a calculus refresher. Or if I had to teach Deep learning, I would probably first explain what's a neural network. My recommendation followed a structure. You could even swap out Digikey product description pages for Wikipedia, I couldn't care any less if it just has to introduce what not how. But when it comes to teaching "how the stuff works", anything less than showing biases, polarities & charge flow is a handwave. I am not making arguments for the sake of arguments - if anyone thinks they got it without touching those, they are tricking themselves in.
