(Myself, I've been heard complaining that git is overly complex, but the source code control systems that I used to use before git include Subversion, CVS and various Rational products and I have no desire to go back to any of them.)
I catch up on a forum a few times a year, asking myself if it's ready for me to switch a repo or two over and see how it goes. So far I have to answer no, but I'm hoping it's just a matter of time.

Like a new filesystem, you should have a backup system in place if you use this, but the system is being well tested.
