I've been hearing about upcoming cures to horrible diseases two or three times a month for several decades and the number that pan out is a rounding error. The only noteworthy development I can think of over the past decade is a 'cure' for peanut allergies (and when I looked into it closer, it turns out it's not even a complete cure). There's apparently neither any incentive nor stomach for humanity to be realistic about how much progress we really make, which, though considerable, is not breathtaking.
