I actually feel and do the exact opposite. I find code on slides to be boring. When I present I want to give the audience an experience like they will have. Live coding can do that well. But it certainly can go bad quick. Live coding on stage takes a TON of practice. Most presenters don't put in the prep so it comes out boring and fail-prone.

Probably the most important thing I've learned in 10 years of tech presentations is that every person in the audience learns in a different way and wants something different. You can't please everyone no matter what you do.
