I like writing by hand, but I don’t agree with the logic that it’s good because it recruits more areas of the brain. The less effective the medium is, the more of the brain it will recruit; chiseling on a stone tablet is probably a more complex task and it probably gives a more broad stimulus to the brain, but it does not mean it’s such a good idea. I would personally prefer to use a text editor for effective writing and then crochet for fine motor skill.
