Unfortunately, medical technology is not even remotely advancing exponentially. The rate of new drug approvals is decreasing (and costs are rising); we are appallingly bad at turning biochemical knowledge into medical technology.
Now, I know you weren't talking about drugs as such, but they are a reasonable proxy for our ability to understand a biological system and then intervene. And the state of the industries that try and do this, strongly suggests that we haven't got a clue.
Just to lay the pessimism on a little thicker, we may even be lucky to stay where we are, given the spread of antibiotic resistant bacteria.
Never mind immortality, I'd be happy to know that we still have working antibiotics when I roll up to hip replacement age!
