I have no doubt there is huge amount of people who love the exceptions, and I agree with you that is precisely this crowd that pushed this agenda forward.
But I found following true, anything that can fail will fail. E.g. any type of IO operation. It's not a question of if but when. What that means I have a problem when people think IO Error is an exceptional state of some kind. It is not, it's just valid return value of the given IO operation, if I think of it as such I write code that is more reliable and testable. As for panic/recover - given the above when would I really want to panic? If I treat my errors as first class citizens, I don't ever need to panic. And for the record I myself have on few occasions reached for panic (this will never happen type of thinking) - and I found myself going back and replace it with proper error handling every single time. So now I just know better. As for the argument that it is possible to use try/catch type of error handling successfully. I say I don't doubt it - I just never had the pleasure to work with (or after) anyone that was able to do that. And I include my own try/catch code in that group.
