How much of that needs to relate to the memory usage though? Embedded media doesn't need to be loaded besides what's visible in the current channel and perhaps a bit of scrollback, perhaps some text and scrollback for other frequently viewed channels. Livestreams also shouldn't be taking memory unless you're watching, same with voice. Avatars and emotes would certainly take memory, but certainly not hundreds of megabytes of it.
