I prefer Igloo IRC, but finding a server and chatroom is an exercise you'll have to do on your own depending on what you are looking for. I would start with Freenode if you don't know where to begin.
As a musician, I can tell you that practicing a song (particularly a well known song) is very frustrating partly due to boredom. A practiced musician will know when they’ve reached their limit for the day of learning a song. Muscle memory is much slower than neural memory, and usually requires “sleeping on it”.
Knowing you’ve reached the limit of your current capability is boring because you know the next few practice rounds will be much of the same, with minor improvements that provide a dopamine rush.
Regardless, nothing has changed in the age-old saying of how to get to Carnegie Hall: Practice, Practice, Practice. The practice is the boredom, but without training your muscles and building up myelin sheaths, you’ll never be good enough to automate most of the music to an extent that you can improvise on top of it (the fun part).
I guess my point is akin to OP’s, in that boredom isn’t inherently a bad thing, but a means to an end. Without the boring practice, we wouldn’t have experts/artists...and even then, the practice doesn’t have to solely be boring.
