Julia is fast becoming one of the great programming languages of our era. Julia is not going away, its usage is only becoming more pervasive. Imagine if you had learned Python 20 years ago. Julia's founding sponsor is Dr. Jeremy Kepner [1] who is the founder of MIT Lincoln Laboratory Supercomputing Center [2] and the founder of GraphBLAS [3]. Kepner's got a good eye for things, he knows what's coming down the pipe and what will be important in a language of the future. Learning Julia now means you'll be ahead of the curve for years to come. Your time will not be wasted.
