The ballpoint’s universal success has changed how most people experience ink. Its thicker ink was less likely to leak than that of its predecessors. For most purposes, this was a win—no more ink-stained shirts, no need for those stereotypically geeky pocket protectors. However, thicker ink also changes the physical experience of writing, not necessarily all for the better.
While I disagree with the premise, that cursive was killed by the ballpoint pen, I agree with some of the points made to support the argument such as the one above.
