Clarification, due to the other person's (now flagged) comment: https://news.ycombinator.com/item?id=42163157
None of this is meant to ridicule anyone. If using Discord for home automation works, great, have fun at it, feels like a cool way to have a hacker mindset (not to discount the arguments that suggest that there are also other alternatives).
I still think that describing a popular chat platform as a highly available message queue is funny though, because that's a very unconventional way of looking at things.
"Thanks, I'll base my next enterprise project on Discord as the message queue of choice."
Hah, what an amusing way to look at things, thanks for that.
