but the tone tag here isn’t necessary, since like you said “People would be able to tell that they’re not in 2048 because that’s not possible”
but someone might not know that you're joking and could think that you're genuinely confused (i think that's @mybearworld 's point)
That I’m joking? I know what tonetags are and that they are helpful non some contexts but aren’t here (people should know you aren’t in 2048 as time travel isn’t possible), which is what I’m joking about
people might not know that @KuromiNotTaken was joking. (they might think that @KuromiNotTaken is confused)
Are you serious? People might not know that someone saying that they are in 2048, a year 15 years away, is joking, and instead may be confused what year they are in? How can you be confused what year you’re in, let alone think you’re in a year in 25 years? Is this how woke we’ve become?
