Oh, no! Suddenly I speak a different language than everyone else. Instead of learning a second language (too much work, you know), I think I'll find a few strangers who still speak the same as I and forsake my home and family and mount a trek to the other of the planet. Then, when we're far enough away from people who speak other languages, I'll forsake all the other aspects of my old Babylonian culture as well: dress, grooming habits, methods of writing, architecture, art, etc. Well, maybe I'll keep some remnants of "Babylonish" religion as well. Unless these beliefs coincide with Judaism, in which case I will corrupt them. Maybe I'll embellish details of the global flood that occured just a few generations ago to start out.
Oh, really! You know this story never made sense to me, not even as a little kid. I wouldn't be surprised if it was authored by the same person or group who wrote The first creation account and the Fall of Man. God is paranoid of mankind and determined to stunt their progress, first by making false death threats to keep humans from the Tree of Knowledge of Good and Bad, second by throwing them out of Eden to keep them away from the Tree of Life, and finally by disrupting the building project to keep man from entering heaven itself. Also note Genesis 11:7:
Come now! Let us go down and there confuse their language that they may not listen to one another's language.
Who is the "us?" It's the same "us" from Genesis 1:26 and 3:22; the plural "gods" from Genesis 1:1 who created the heavens and the earth. For some reason they always get omitted, and we hear that "In the beginning God created the heavens and the earth."
