I'm surprised that you never have bugs of the type "this thing is nil and I didn't expect it to be". This is by far the most common type of bug I see in production Ruby applications and it simply can't happen with something like Sorbet.
Null is simply the most frequent example of this issue. Getting an integer rather than a string is super common, for example. Or a string instead of a date.
What does super common mean? Do I see these bugs once a month? No, I do not. Null exceptions are common I agree with that. For me its not enough to appreciate something like Java or Go but I understand the argument.
