Whether you write bold R, Z, Q, C or blackboard bold for these number sets nobody at all is going to be confused – they appear in both ways all over the place in books and research papers – and if you mix ordinary bold R, Z, Q, C next to the blackboard bold versions of the same upper-case letters in a single document then your friends should tell you to knock it off. As for "where things are going" – this has been changing extremely gradually over the past 60 years. If the trend accelerates maybe you'll stop seeing both variants in wide use in about another century. |

That sounds about right. Maybe even 50 years, but it is a rather slow process.
