What you say may be true now, but I, who speak Spanish as a second language, refuse to quit speaking it because I love the musicality of it. I also like (don't ask me to name them..stern look) the alternative ideas that can easily be expressed in Spanish but not English. It works both ways.
I also had a professor at WMU that claimed that the Hispanic population in the USA would reach majority percentages by 2010-2020. Of my children who grew up with Spanish as their first language, my daughter is still fluent and presently teaches Spanish at the secondary level.
My son is lucky if he can say tortilla correctly, but then he always did succumb easier to peer pressure. My main point is that soon it may be cool to speak Spanish and that is what the young will do, so practice rolling those rrrs(look Ma, no apostrophe!)
