I take your point, but "fiendishly difficult"? I think you're
exaggerating.

True, but is there any evidence that this constitutes a security risk?

Lots of things (such as TLS, ssh) can theoretically be brute forced -
the question is whether such brute forcing is sufficiently practical to
be a threat. I have seen nothing to indicate that properly configured
WPA2 can be realistically brute forced.

Of course not - they never are ;) The trick is to pick a good one, and
for wifi, that's WPA2 using AES.

I suppose, but my impression is that most hardware from the last few
years is fine.
