Otiose: serving no useful purpose, futile.
As in, “When it’s cold out, it seems a bit otiose to indicate that you want tea, Earl Grey, hot. Of course you want hot tea in the dead of winter, Jean Luc. Similarly, it would be otiose to resist the Borg. Those guys don’t take no for an answer. This concludes Your Guide to Starship Enterprise Basics, Day One.”
Does anyone out there not associate the word “futile” with the Borg? I have a skewed survey sample because I grew up watching ST:TNG and all of my adult friends are nerds. So I’m sorry if it looks like I took the easy way out of illustrating otiose, but now I can say I have illustrated a Borg. That's going under the “Nerdery” header on my resume.
