Yes and no. Whether or not you should use a word depends on whether the word will be understood to mean what you want to convey when you use it. If you mean “agile” in the original way, but people hear “agile” and think you mean the modern so-called “agile” (full of bureaucracy, and many people actually hate it), then communication will fail. Therefore, using the word “agile” will fail to aid in communication, and you should stop using the word for that. If you want to wage a campaign to change people’s understanding of the word, please do, and I wish you luck. But you can’t simply use a word and then pretend that the fact that people misunderstand you is somehow their fault.
