There's two ways this argument goes awry: "IRC is fine, you just have to be smart enough" and "Only ever use IRC for the things it does well", I thought we were on the other branch there for a bit.
I had specifically included a scenario that is both common for use in my experience, and also pretty much impossible for a normal human using IRC in order to preempt this branch:

Sure, in extremely limited situations (so many qualifications are required here I won't list them) it's mostly easy enough for a non-technical person to manage.
Normal people (that is, people who value their own time and haven't been warped by daily interaction with software that fails to do what you asked because you failed to include some extremely implicit punctuation) laugh at many common explanations surrounding IRC, just a handful of examples: "IRC doesn't have passwords really so to prove who you are, you have to speak specific commands, like a CLI, at this bot over here, or configure your client to do that for you" "IRC has away status but nobody really uses it, because it's manual in many clients, so you typically 'ping' people and just wait to hear back if they are around" "oh yeah, if you want to get rid of all the join/part/away spam, the option for that is hidden in a menu with a bunch of other stuff, and in this client you have to set it up for each channel separately" "oh, yeah, you can't speak in that channel because you have to get the bot to +v you by direct messaging it 'shibboleth'" "btw here's the list of random-seeming letter 'flags' our server supports and how it interprets what they mean differently from other IRC daemons"
And we haven't even talked about how bad the story is around message persistence or using multiple clients or the "solution": bouncers. Getting all that going is basically a non-starter for humans unless you give in and use a service like IRCCloud that deals with search and synchronization well across platforms (but which you must be aware of in the first place).
I'm pretty technical, I've internalised the arcane knowledge, I've written IRC RFC-compliant bots to get things done (and then made them conform with common out-of RFC conventions in order to work with non-conforming IRCds), but that was all in high school, well before I gained a sense for the value of my own time. I can do it but I still refuse (to the degree that a team's use of IRC would make me pass on an offer as would I pass on a developer interviewee's inability to perceive usability problems with IRC).
