People used to say that about 4 gb cards
There are probably more images lost because of dropped and lost cards while changing them than by card failure. Just because you have a big card does not mean you have to fill it up before you change it. It just gives you more room for continuous shooting if needed. With the size of the latest backs, those bigger cards will become more and more common. And much less expensive.
I'm just going to throw a note of caution out there. If a card this size goes bad, imagine losing 128GB of images. Just saying.
