I don’t think cursive was ever actually useful. The best you could ever really hope to get out of your cursive is that your cursive would be so pretty that someone would be impressed and if they were superficial enough would like you because of your pretty hand writing. It’s not faster than printing, it’s not easier than printing, for most people it’s not more legible than printing, it really has always been only useful as a simple substitute for calligraphy.
Thought control will never happen. People are too scatter brained. They’d be there thinking their dictation and then a hot chick shows up on TV then all of a sudden “holy crap are those real” winds up in their contract.
We will certainly need a “ta ta” filter on the output.
