You are missing the point. There is a fundamental difference in
say Illustrator and a programming language. With a program like
Illustrator, the expectation is you are editing or creating a
document interactively. Here, dialogs that warn before doing
something that cannot be recovered from are reasonable. The same
would be true for Mathematica *if* the only usage mode of
Mathematica was a similar interactive mode. But Mathematica
implements a general programming language. Such warnings add
overhead any program created and halt the program for user
interaction. Neither of these outcomes are desired in a
programming language. So, similar warnings in a programming
language are not at all reasonable.

The particular function that started this sub-thread was
DeleteFile. Surely, there can be no doubt as to the intent of
this function. I see no need to ask a user "Are you sure?" with
such a clearly descriptive name. Frankly, there is no viable way
to protect a user who would carelessly use DeleteFile. For a
careless/inattentive user, a dialog asking "Are you sure?" gets
a click on the OK/Yes button with no real thought. And the end
result is precisely the same.
