Agree. Transistors really are worth learning about to any level - its certainly possible to get lost in the physics.

I’d find some high level tutorials online that maybe use one of the free circuit simulator tools.

Nice animation on this site

If you are really curious there are many simple circuits you can build.

It’s quite a thrill to get an LED to blink with a self built circuit.

I’m also a crusty old sw eng. I did spend sometime being a young electronics engineer.

Good luck with the journey.
