I just want to add that the criticisms on presentation are not  called for. I don't usually get involved in these kind of discussions, but Silverblade33 is correct. I can do something perfectly, then faced with an audience, I can make mistakes and get flustered. I have been teaching since 1966 before many of you were born. While I don't know Ami, I take offence that you can criticize her presentation.

Anyway, the discussion is on Vue 8 and its new features. let's stick to that topic.
