I will say that in sfortware you can estimate but because there are many unknown things it's difficult.

Is a bit like "How long it will take to discover the cure for cancer?"

Yes!

"We have this problem, you see, where cells sometimes start to multiply aggressively instead of doing their job. That's a bug, the customers are complaining. How long will it take to fix it? What do you mean you don't know - not even a ballpark estimate?"
