I'm a little late to the topic, but I am a Millennial, and I can read and write cursive. Of course, I also do calligraphy in English and Hebrew, and hand draw fonts for logos... So I feel like I may be atypical for the whole handwriting stuff.
As an archaeologist, I have found that being able to read cursive is in fact a valuable and dying skill. Most of my younger co-workers have to rely on other people's parsing of old documents. When you are trying to track down the details of folk's lives from 150 years ago using Census records and the like, relying on other people's ability to figure out what Joe Enumerator meant by a given squiggle is not very advisable. I really appreciate that my elementary really pushed cursive writing. It had very little practical application back when I did security work, but since my career change, it has really come in handy.
