Ive been writing Go for over a decade and I still feel like I never quite "got" channels. Every time I use them I need to go consult the manual, and none of the patterns feel obvious which is weird considering the rest of the language feels very obvious.
Too many years of Java and managing Threads and Runnables probably rotted my brain.
Channels are honestly one of the most over-used things in Go. I've been writing Go professionally since 2015 and I honestly rarely use them. Programmers new to Go love to shovel them in everywhere because "why use Go if you're NOT going to use channels?" and I have to say sorry, no - write it serially, then determine if it breaches your SLOs, THEN determine if concurrency fixes it.
I’d say it’s important to understand how they work but I also rarely find myself reaching for channels. I see more usage of wait groups and mutexes, but even then you can build abstractions around these in a way that can be reused without having to touch them again.

I've started using golang last year and I feel like I'm missing exactly this kind of experience with these patterns
