It's the field - very wide range of ability. Some are stoked about making LEDs blink and others are busy dumping and reverse engineering ROMs. Just depends on one's own journey stage. In my case article is above my level...haven't dealt with UART before

Agreed, its a nice accessible article for beginners. I can see someone who has really only played with Arduinos and Adufruit modules looking at this and getting some inspiration to try out some of the techniques he mentions.

For example, you'd be suprised how many practicing EEs I've met who aren't aware drag soldering is a thing. (Which is a fantastic technique btw, saves so much time and gets you much nicer joints than individually soldering )
