Yes, typing is usually faster than cursive. However, most keyboards are not ergonomic and years of use at high speeds will most likely lead to RSI or at least sore wrists. And there are still be plenty of times in life where writing something by hand is more appropriate than typing it up.
You only get RSI if you type vastly more than you could write by hand. As for the times when typing is inappropriate, those are relatively short notes for which cursive is unnecessary. So far in my life I have come across 0 legitimate uses for cursive.
