If you're giving the idea that cursive improves retention and learning then I would say yes definitely.

It's a revision technique you can use for every exam, at the cost of what? a year of lessons once a week or so? (I have no idea how long cursive is learned for to be fair, I just learned to join writing in English while learning other stuff, seems like a weird thing to specifically have a lesson for to me).

My point is you're not going to learn a meaningful amount extra with that time, you're already dividing your time by 10 or so subjects, having 10% more learning in each subject for 1 year out of the 11-15ish years in education won't make a noticeable difference, certainly not more than learning an effective revision method for exams.

Just my opinion anyway. As a kid I used to argue with teachers all the time that I shouldn't have to write things by hand because I'd be typing the rest of my life anyway. That doesn't help in office meetings taking notes though and even when I have a laptop the notes are no better honestly. I feel like if I learned to write then barely did it ever again it would be so slow that it would be a genuine disadvantage.

You'll give it to me? Thanks I guess. All I've seen are studies that show the brain learns better when using handwriting over typing.

I also tend to have a smartphone on me all the time, but if I'm in a situation to take notes, I'll always bring some writing implement. I'm not taking notes in an office meeting on my phone for numerous reasons and even when I'm at a multiscreen computer I still want to take physical notes.
