Who knows. But it's not like she'll be completely forgotten, though. And by the way, people need to realize that just because ONE song flops that it is not the end of their career. How long she lasts is ultimately up to her, she definitely has it in her.
Hard to tell. I'm almost certain Lady Gaga won't release generic singles in her 50's in an attempt to remain relevant, and if she doesn't do that then she can never match the length of Madonnas career. But if she stops while she's ahead it's not necessarily a bad thing.
