Not all schools have those and not everybody can practice those at home while every school can teach cursive and every student can practice it at home. It is simple as that.

You could make the same argument about teaching children to sing and play instruments in music class given that we now have AI generated music. You could also make the same argument about teaching kids how to draw or paint given that we now have cameras and 3d rendering.

Would you agree with that argument? Why or why not?
