Oh the poor babies!
I remember sitting in lessons where the teacher would dictate something for us all to take down (it saved them having to write it all up on the board for us to copy, plus they could control the speed we wrote it down) and as much as I have very neat, legible handwriting, I'm left-handed and as every southpaw will agree, handwriting is far more difficult for us as we have to 'push' the pen whereas right-handed people 'pull' the pen across the page.
In the 70s and 80s, we were told that we would be marked down both in class and exams if our handwriting was scruffy or difficult to decipher and indeed for poor spelling/grammar.
I do agree that these days, multiple choice exams should be done online for ease of marking and as such I guess long laborious essays could be too, but time allowances for said essays would need to be slashed in light of the time it takes to type a 1,000 word piece of work compared to handwriting it, many students can easily type at a rate of 70+ words a minute, even 50 wpm is fairly easily achieved by kids these days, whereas handwriting takes maybe 4 times this long.
For exams where shorter written pieces are required, I would say there's still a place for handwritten papers.
Clearly, for computerised exams, spellchecker and internet access would have to be removed, although I would say that spelling and grammar should still be part of the marking criteria otherwise what is the point of teaching kids these skills?
These days, I'm grateful to always have access to and choice to use both pens/paper and my phone/laptop as sometimes one is quicker than the other or long/short-term storage of information will determine which I use, as well as the daily state of my arthritis.
I would also add that having worked on computers for a couple of decades before I was forced to retire at 41, the arthritis was exacerbated to the point where I've had to have bones removed from my thumbs to help with pain and movement and I've also had to have carpal tunnel surgery too.
My surgeons did say to me that 20 years from now, the amount of people needing to have these surgeries will go through the roof because people (especially kids) spend so much time 'typing' or playing games with two thumbs on their phones, and cases of RSI will also likely explode due to computer use, both of which could be slowed down by people typing less and doing a little handwriting for a change.
